1. Precautions on disassembly and reassembly

[Bold] numbers in the descriptions below correspond to item numbers in the Parts List and the exploded

assembly diagram for the Model CH 36DL.

Before conducting any repair, make sure to remove the battery (Type BSL 3620, BSL 3626 or BL 36200)

from the product. Otherwise, the motor will suddenly start to run. This is very dangerous.

1. Removing the bottom cover ass’y

(1) Remove the Bottom Cover Ass’y [38] by removing four Tapping Screws (W/Flange) D5 x 20 (Black)

[40] that secure the Bottom Cover Ass’y [38] to the main unit.

(2) Slide the Cam Rod Holder [39] in the direction of the blade. Then remove the Washer [33] (bottom

cover), Cam Rod [34] (bottom cover), Gear [35], First Gear [37], Cam Rod [34] (housing), and Washer

[33] (housing). Lastly, remove the Cam Rod Holder [39].

2. Removing the blade ass’y

Be sure to attach the Blade Case [48] before removing the Blade Ass’y [47].

(1) Raise the Blade Ass’y [47] imbedded into the housing toward the bottom cover. Then remove the

Cushion [29], Spacer [30], and Blade Ass’y [47]. If the Blade Ass’y [47] is too tightly imbedded and

cannot be removed, loosen the Tapping Screw (W/Flange) D4 x 20 (Black) [26] securing the housing in

place near the Blade Ass’y [47], and then remove the Blade Ass’y [47].

3. Removing the blade and the spacer

Remove two Hex. Socket Hd. Bolts (W/Button) M6 x 25 [31] and two Nylon Nuts M6 [28]. Then remove

the Spacer [30]. Two Hex. Socket Hd. Bolts (W/Button) M6 x 25 [31] on the edge of the blade can be

loosened by inserting a hexagonal wrench through the holes at the top and bottom of the blade.

4. Removing the sub handle ass’y

Remove two Machine Screws (W/Washers) M5 x 30 [10]. Then pull the Sub Handle Ass’y [1] outward to

disengage it from Housing (A).(B) Set [23].

5. Removing housing (B)

(1) Remove twelve Tapping Screws (W/Flange) D4 x 20 (Black) [26] so that housing (B) can be removed with

all internal parts stored in housing (A).

(2) Grip the Motor DC 36 V [16] and lift housing (A) so that the power supply section (Motor DC 36 V [16],

Switch [8], Controller (W/Ferrite Core) [19], and Battery Terminal [22]) can be removed in its entirety.

(3) Remove the Rubber Cushion [25], Trigger [21], and Push Pin [13] while making sure that Spring (B) [20] on

Trigger [21] and Spring (D) [9] on Push Pin [13] are not mislaid.

6. Disassembling the power supply section

(1) When disconnecting the internal wire (black) for the Motor DC 36V [16] from the Switch [8], remove

the solder with a soldering iron. When disconnecting the internal wire (red) from the Connector 50092

[5], cut the Connector 50092 [5] connection with nippers.

(2) The Controller (W/Ferrite Core) [19] is soldered to the Battery Terminal [22] and two Switches [8] with

internal wires.

(black) for the other Switch [8], remove the solder with a soldering iron.

(4) When disconnecting the internal wire (red), internal wire (black) and internal wire (white) for the Battery

Terminal [22], remove the solder with a soldering iron.

NOTE: Do not disassemble the Switch [8] and the Controller (W/Ferrite Core) [19].

Conduct reassembly by doing the disassembly procedure in reverse. Note the following:

1. Connecting the power supply section

(1) Make sure all connections are made by referring to the connecting diagram. Always pay attention to

the color of the internal wires and the terminals to be soldered.

(4) Pay attention to the soldering direction when soldering the Controller (W/Ferrite Core) [19] to two

Switches [8] and the Battery Terminal [22].

(5) Attach the Motor DC 36 V [16] and the assembly of the Controller (W/Ferrite Core) [19], two Switches

[8], and Battery Terminal [22] onto housing (A) of Housing (A).(B) Set [23]. Ensure indented portions

on the Motor DC 36 V [16] are placed on protruding portions of housing (A).

(6) Attach the Trigger [21], Spring (B) [20], Push Pin [13], Spring (D) [9], and Rubber Cushion [25] to the

correct locations on Housing (A).(B) Set [23]. Ensure Spring (B) [20] is attached at right angle to the

Switch [8]. Spring (B) [20] is securely fastened and is not bent or misaligned.

2. Reassembling the housing section

(1) Ensure internal wires do not sag and are not pinched when covering with housing (B) of Housing

(A).(B) Set [23]. Also, ensure Spring (B) [20] is securely fastened and is not bent or misaligned.

(2) Press Protector [11] into Housing (A).(B) Set [23] while firmly holding packing (A).

(3) Align housing (B) of Housing (A).(B) Set [23], and tighten twelve Tapping Screws (W/Flange) D4 x 20

(Black) [26] after inserting the Ball Bearing 626ZZC2 PS2-L [36] and the Ball Bearing 608DDC2PS2L

[32] into the ball bearing chambers on the housing. (Tighten the screw “A” shown on the wiring

diagram first and ensure the internal wires are not pinched.)

(4) Pass Shaft (D) [4] through the hole on the Push Pin [13]. Make sure the protruding portions on the Sub

Handle Ass’y [1] are aligned with the indented portions on Housing (A).(B) Set [23]. Then tighten two

Machine Screws (W/Washers) M5 x 30 [10]. Make sure the two Nuts M5 (Black) [14] do not fall off.

(5) Insert the felt flange into the groove on Housing (A).(B) Set [23].

3. Attaching the blade and gear

(1) Pass two Hex. Socket Hd. Bolts (W/Button) M6 x 25 [31] on the edge of the blade through the Spacer

[30]. Then pass a hexagonal wrench through the holes at the top and bottom of the blade and tighten

the two Nylon Nuts M6 [28]. The protruding portion of the Spacer [30] must be facing the edge of the

blade.

(2) Attach the blade to Housing (A).(B) Set [23]. If the Cushion [29] is too tight and cannot be inserted,

loosen the Tapping Screws (W/Flange) D4 x 20 (Black) [26] around the Cushion [29] and then attach it.

Retighten the Tapping Screws (W/Flange) D4 x 20 (Black) [26]. Replace the Cushion [29] if it is

scratched or cracked.

(3) Apply grease (Shell Alvania Grease RL3) to the inside of the Cam Rod Holder [39] and pass it through

the blade. Make sure the wedge-shaped joint on the Cam Rod Holder [39] faces toward the HITACHI

logo on housing (A) at this time.

(4) When attaching the First Gear [37], apply grease (Shell Alvania Grease RL3) to the tooth surface on

the First Gear [37] and insert the Ball Bearing 626ZZC2 PS2-L [36].

(5) Apply grease (Shell Alvania Grease RL3) to both sides of the Cam Rod [34] (on the housing side), and

the inner diameter of the cam alignment hole and the interlocking hole on the blade pin. Then press

them onto the housing blade's pin. Ensure the Cam Rod [34] is attached with the shear droop surface

and insert the shaft of the Gear [35] into the Ball Bearing 608DDC2PS2L [32]. Ensure the Cam Rod

[34] and the Gear [35] are interlocked.

(7) Apply grease (Shell Alvania Grease RL3) to both sides of the Cam Rod [34] (bottom cover), inner

diameter of the cam alignment hole, and interlocking hole on the blade pin. Then press them onto the

blade pin and the Gear [35] cam. Place the Washer [33] on the shaft of the Gear [35]. Ensure the

Cam Rod [34] is attached with the shear droop surface facing the Gear [35] (on the blade).

(8) Slide the Cam Rod Holder [39] toward the Gear [35] so that it sandwiches the two Cam Rods [34] and

the blades (upper and lower).
