DOUBLE INSULATION FOR SAFER OPERATION

To ensure safer operation of this power tool, HITACHI has adopted a double insulation

design. “Double insulation“ means that two physically separated insulation systems have

been used to insulate the electrically conductive materials connected to the power supply

from the outer frame handled by the operator. Therefore, either the symbol “

” or the words

and “Double insulation” appear on the power tool or on the nameplate.

Although this system has no external grounding, you must still follow the normal electrical

safety precautions given in this Instruction Manual, including not using the power tool in wet

environments.

To keep the double insulation system effective, follow these precautions:

䡬 Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this

power tool, and only genuine HITACHI replacement parts should be installed.

䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy water,

and dry thoroughly.

Never use solvents, gasoline or thinners on plastic components; otherwise the plastic

may dissolve.

not, bring the tool to a HITACHI AUTHORIZED SERVICE CENTER for repair.

2. Power source

Ensure that the power source to be utilized conforms to the power source requirements

specified on the product nameplate.

3. Power switch

Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while

the switch is in the ON position, the power tool will start operating immediately and can

cause serious injury.

4. Extension cord

When the work area is far away from the power source, use an extension cord of sufficient

thickness and rated capacity. The extension cord should be kept as short as practicable.

WARNING: Damaged cord must be replaced or repaired.

5. Prepare a wooden workbench (Fig. 5)

Since the saw blade will extend beyond the

lower surface of the lumber, place the lumber

on a workbench when cutting. If a square block

is utilized as a workbench, select level ground to

ensure it is properly stabilized. An unstable

workbench will result in hazardous operation.

CAUTION:

To avoid possible accident, always ensure that

the portion of lumber remaining after cutting is

securely anchored or held in position.

6. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact

a licensed electrician to make appropriate repairs.

If such a fautly receptacle is used, it may cause overheating, resulting in a serious hazard.

7. Confirming condition of the environment:

Confirm that the work site is placed under appropriate conditions conforming to

prescribed precautions.

ADJUSTING THE SAW PRIOR TO USE

1. Adjusting the cutting depth (Fig. 6, Fig. 7)

To adjust cutting depth, loosen the clamp lever

and, while holding the base with one hand,

move the main unit up and down to obtain the

prescribed cutting depth. Inch scale on the saw

cover and metric scale on the link provide a

general guide to cutting depth. After adjusting

to the prescribed cutting depth, tighten the

clamp lever securely.

2. Adjusting the angle of inclination

As shown in Fig. 8 by loosening the wing-bolt

on the inclined gauge, the saw blade may be

inclined to a maximum angle of 45° in relation

to the base. Always insure that the wing-bolt is

thoroughly tightened after making the desired

adjustment.

3. Regularing the guide (Rip fence)

.......................................... Optional Accessory

The cutting position can be regulated by moving

the guide to the left or right after loosening its

wing-bolt. The guide may be mounted on either

the right or left side of the tool. (See Fig. 9)

CUTTING PROCEDURES

CAUTION:

● Recheck that the saw blade is securely clamped.

● Confirm that the clamp lever for adjusting the

cutting depth, the wing-bolt for adjusting the

angle of inclination.

● Grip the saw as shown in Fig. 2 and be sure the

cord is free to move through the entire cut

without jamming or getting in the path of the

saw blade.

1. Place the saw body (base) on the lumber, and as

in Fig. 10 align the intended line of cut with the

saw blade, using the notch at the front of the

base. This relationship of base to lumber should

remain unchanged regardless of the inclination

of the base.

2. The switch should be turned to the ON position

before the saw blade comes into contact with

the lumber. The switch is turned ON when the

trigger is pulled by one’s finger, and is turned

OFF when the trigger is released.

be cut.

3. Push the safety cover lever all the way back so

the blade is exposed as shown in Fig. 11.

4. Tilt saw forward and align the notch (Fig. 10)

with the pre-marked guide line.

5. Release the safety cover lever. When the safety cover contacts the workpiece surface, it

will be in proper position to open freely when cutting is commencend.

6. Holding the saw in position, with the blade not contacting the workpiece surface, pull the

trigger.

7. After the saw has reached full speed, gradually lower rear end of the saw until its base

rests on the work surface.

8. Advance saw along the cutting line up to the corner.

9. Release trigger and allow blade to stop completely before withdrawing the blade from

the workpiece.

䡩 Never under any circumstances pull the saw backwards while the blade is in motion, as

kickback may result.

2. NE JAMAIS UTILISER L’OUTIL SANS QUE TOUS LES DISPOSITIFS DE SECURITE NE

SOIENT EN PLACE.

Ne jamais faire fonctionner cet outil sans que tous les dispositifs et caractéristiques de

sécurité ne soient en place et en état de fonctionnement. Si un entretien ou une réparation

nécessite le retrait d’un dispositif ou d’une caractéristique de sécurité, s’assurer de bien

remettre en place le dispositif ou la caractéristique de sécurité avant de recommencer à

utiliser l’outil.

3. TOUJOURS SE PROTEGER LES YEUX ET LES OREILLES.

Pour se protéger des projections de copeaux de bois, particules métalliques ou autres

débris, porter des lunettes de protection ou un masque pour les yeux. Porter des

protections anti-bruit pour se protéger du bruit.

4. SE PROTEGER CONTRE LES DECHARGES ELECTRIQUES.

Empêcher tout contact du corps avec les surfaces mises à la terre, par exemple tuyaux,

radiateurs, plaques de cuisson et enceintes de réfrigération. Ne jamais faire fonctionner

l’outil dans un endroit humide ou mouillé.

5. DEBRANCHER LES OUTILS.

Ne jamais laisser l’outil branché dans une source d’alimentation. Toujours débrancher

l’outil de la source d’alimentation avant tout travail de réparation, d’inspection, d’entretien,

de nettoyage, de remplacement ou de vérification des pièces.

6. EVITER TOUTE MISE EN MARCHE INOPINEE.

Ne pas transporter l’outil pendant qu’il est raccordé à la source d’alimentation. Ne pas

transporter l’outil avec le doigt près de l’interrupteur d’alimentation. Bien s’assurer que

l’interrupteur d’alimentation se trouve sur la position “OFF” (arrêt) avant de raccorder

l’outil à la source d’alimentation.

7. REMISER L’OUTIL CORRECTEMENT.

Lorsqu’on ne se sert pas de l’outil, le remiser dans un endroit sec. Veiller à ce qu’il soit

hors d’atteinte des enfants. Fermer le local de remisage à clé.

8. MAINTENIR L’AIRE DE TRAVAIL PROPRE.

Les aires de travail et les établis encombrés favorisent les accidents. Débarrasser l’aire

de travail et les établis des outils inutiles, débris, meubles, etc.

Français

9. CONSIDERER L’ENVIRONNEMENT DE L’AIRE DE TRAVAIL.

Ne pas exposer les outils à la pluie. Ne pas les utiliser dans un endroit humide ou mouillé.

Veiller à ce que l’aire de travail soit bien éclairée et bien aérée.

Ne pas utiliser l’outil en présence de liquides ou de gaz inflammables.

Les outils projettent des étincelles pendant qu’ils fonctionnent. Ne jamais utiliser les

outils dans un lieu renfermant de la laque, de la peinture, du diluant, de l’essence, des gaz,

des produits adhésifs ni aucun autre matériau combustible ou explosif.

10. ELOIGNER LES ENFANTS.

Ne pas laisser les visiteurs toucher l’outil ou le cordon de rallonge.

Tous les visiteurs devront être suffisamment éloignés de l’aire de travail.

11. NE PAS FORCER L’OUTIL.

Il effectuera le travail le meilleur et avec la sécurité maximale au régime pour lequel il a

été conçu.

12. UTILISER L’OUTIL CORRECT

Ne pas forcer sur un petit outil ou accessoire pour faire le travail d’un outil de grande

puissance. Ne pas utiliser un outil pour un usage pour lequel il n’a pas été prévu: par

exemple, ne pas utiliser une scie circulaire pour couper des branches d’arbre ou des

bûches.

13. SE VETIR CORRECTEMENT.

Ne pas porter de vêtements lâches ni de bijoux. Ils pourraient se prendre dans les pièces

en mouvement. Il est recommandé de porter des gants en caoutchouc et des chaussures

anti-glissantes lors d’un travail à l’extérieur.

Porter un couvre-chef qui recouvre les cheveux longs.

14. PORTER UN MASQUE, UN MASQUE ANTI-POUSSIERE OU UN APPAREIL RESPIRATOIRE

SI LE TRAVAIL DOIT DEGAGER DE LA POUSSIERE.

Toutes les personnes présentes sur l’aire de travail devront également porter un masque,

un masque anti-poussière ou un appareil respiratoire.

15. NE PAS MALTRAITER LE CORDON.

Ne jamais transporter l’outil par le cordon ni tirer brusquement sur le cordon pour le

débrancher.

Eloigner le cordon de la chaleur, de la graisse et des surfaces tranchantes.

16. FIXER LA PIECE.

Utiliser des dispositifs de serrage ou un étau pour tenir la pièce. Cela sera plus sûr que

de tenir la pièce à la main et libérera les deux mains pour le travail.

17. NE PAS TROP SE PENCHER.

Garder une bonne assise et un bon équilibre à tout moment.

18. ENTRETENIR LES OUTILS AVEC SOIN.

Maintenir les outils aiguisés et propres pour optimiser le travail et la sécurité.

Suivre les instructions de graissage et de remplacement des accessoires.

Vérifier périodiquement les cordons d’outil et les faire réparer par un centre de réparation

agréé s ’ils sont endommagés. Vérifier périodiquement les cordons de rallonge et les faire

remplacer s’ils sont endommagés. Maintenir les poignées sèches et propres, et enlever

toute graisse et toute huile dessus.

19. RETIRER LES CLAVETTES DE REGLAGE ET LES CLES.

Les clés et les clavettes de réglage devront être retirées de l’outil avant de sa mise en
