SAVE THESE INSTRUCTIONS

WORK AREA

• Keep work area clean, free of clutter and well lit. Cluttered and dark work areas can cause

accidents.

• Keep children and bystanders away while operating a stacker. Distractions can cause you to lose

control, so visitors should remain at a safe distance from the work area.

• Be aware of all power lines, electrical circuits, water pipes and other mechanical hazards in your

work area, particularly those hazards below the work surface hidden from the operator’s view that

may be unintentionally contacted and may cause personal harm or property damage.

• Be alert of your surroundings. Using a stacker in confined work areas may put you dangerously

close to cutting tools and rotating parts.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when using a stacker. Do not use a

stacker while you are tired or under the influence of drugs, alcohol or medication. A moment of

inattention while operating a stacker may result in serious personal injury.

• Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing

and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving

parts.

• Use safety apparel and equipment. Use safety goggles or safety glasses with side shields which

comply with current national standards, or when needed, a face shield. Use as dust mask in dusty

Page of 10

work conditions. This applies to all persons in the work area. Also use non-skid safety shoes,

hardhat, gloves, dust collection systems, and hearing protection when appropriate.

SEMI-ELECTRIC STACKER USE AND CARE

• Do not modify the stacker in any way. Unauthorized modification may impair the function and/or

safety and could affect the life of the equipment. There are specific applications for which the

stacker was designed.

• Always check for damaged or worn out parts before using the stacker. Broken parts will affect

the stacker operation. Replace or repair damaged or worn parts immediately.

• Do not exceed the stacker load capacity of 2200 lbs.

• Distribute the load evenly. Uneven loads may cause the stacker to tip, resulting in personal injury

to the operator or others.

• Use the stacker on flat and level surfaces capable of supporting the stacker and its maximum

load. Pulling or pushing a load on a slanted or uneven surface can result in loss of control.

• Store idle stacker. When stacker is not in use, store it in a secure place out of the reach of children.

Inspect it for good working condition prior to storage and before each use.

OPERATION

WARNING: Press the power switch to turn OFF power supply if the stacker becomes

out of operators control!

WARNING: NEVER move the stacker when the forks are lifting or lowering!

WARNING: Batteries contain acid! When handling batteries ALWAYS wear approved

safety goggles, rubber gloves and protective clothing that are able to stand up to acid. Acid

can cause burns and injury.

WARNING: Risk of fire can occur when working with batteries. Avoid any open

flame, smoking, or any flammable situations when handling batteries!

BEFORE OPERATION – BATTERY INFORMATION

Battery initial charge:

Charge batteries minimum of 12 hours or until the LED indicator light on panel shows 100%. When

charging batteries, the stacker must be parked in a secure area with good ventilation. Check that all

cables are connected tightly and no signs of damage appear.

Follow any safety regulations of battery manufacturer and any specific instructions according to battery

manufacturer if replacement battery is used.

Page of 10

The battery panel must never be removed before or during charging. An open panel can cause injury

or death from electric shock.

It is recommended to charge the batteries whenever the stacker is not in use. This helps maintain the

life of the batteries.

The ON-Board Charger should always be used for charging batteries with this stacker.

The avg. charge time is 9 to 12 hours for a fully discharged battery.

When the battery is fully charged the charger will automatically transfer to non-charging status to not

damage the batteries.

It is recommended to check water level of batteries every 3 to 6 months (see maintenance section)

Operating instructions

1. Before each use, check that the stacker is in normal working condition. Check moving parts,

hydraulic hoses, wheels, etc. Do not use stacker if not operating normally. Have qualified

mechanic make repairs before use.

2. Check the battery power as indicated in Fig. 1. Pull the general power supply switch out to turn

on the general power supply, unlock the electric lock on the handle, check the electric energy

meter on the instrument panel of the stacker. If the zero end is lit, this indicates there is no power

in the batteries, and batteries need to be charged. Do not operate the stacker without well

charged batteries, as this can greatly reduce the service life of the batteries and damage the

batteries.

3. Check that the stacker lifting and lowering is operating normally.

Operation: Stacking and Handling loads

Turn on the stacker by unlocking the electric door lock. Move the stacker near the load to be

transported. Press the lowering button and adjust the height of the forks to a proper position with

pallet of load. Insert the forks slowly and as deep as possible into the pallet. Press the lifting button

until the forks are 8-12 inches from the ground (8 to 12 inch max. height is recommended when

transporting goods). Move the stacker to the desired location of the load and stop slowly. Keep the

front of the forks minimum of 4 inches from any shelf or racking. Press the lifting button to raise the

forks to a proper height with the shelf or racking. (Keep the bottom of the pallet min. of 4 inches

MAINTENANCE

• Maintain your stacker. It is recommended that the general condition of any stacker be examined

before each use. Keep your stacker in good repair by adopting a program of conscientious repair

and maintenance. If any abnormal vibrations or noise occurs, have the problem corrected before

further use. Have necessary repairs made by qualified service personnel.

Routine maintenance: Routine maintenance is cleaning the stacker regularly, keeping the batteries

clean and charged, and to examine any cords, hoses, or moving parts regularly for wear or potential

damage. Never operate with damaged parts. Always repair any damage to the stacker before using

or operating at anytime.

Maintenance for mechanical system/parts: Perform at least every six months. Add lubricant to the

bearings of the drive wheel and the doorframe. Examine fittings and connections to be sure they are

fully tight. Check the flexibility and condition of wheels, and the door-frame rollers. Check that the

lifting range of forks is operating normally. The operation noise level of the stacker should be no more

than 70dB.

Maintenance for hydraulic system/parts: Perform at least every six months. Check the oil cylinder for

any leakage externally or internally. Check all the hydraulic hose connections for any leakage. The

hydraulic oil should be kept clean and generally should be replaced every 12 months. Only ISO

hydraulic oil should be used. For higher temperature conditions, HL-N46 or HL-N68 should be used;

for lower temperature conditions, HV-N46 or HV-N68 hydraulic oil. Old hydraulic oil should be treated

according to any local rules and regulations.

Maintenance for electric equipment/ batteries: Perform at least every three months. ALWAYS wear

safety goggles and rubber gloves when working with batteries. Every 3 to 6 months, check the level of

the water in the batteries. (only when using no-seal batteries.) Remove battery cap, check if water level

Page of 10

is below fill line. ONLY use distilled water if any water is needed. Replace battery caps securely and

begin charging and using as normal.

Check battery terminals are clean, terminals should be kept clean with Vaseline and tight.
