Description Chain Mortiser
CONCEPT AND MAIN APPLICATIONS
Based on the current model 7104L, its specifications have been upgraded
to meet the European standards. The front cover has been added H
to enclose the cutter chain. Some electrical parts have been changed to
comply with the electromagnetic compatibility-requirement.
This tool is ideal for making mortises and notches quickly. Pivoting chain
bar enables an opearator to make a 130mm long rectangular hole in
L
three cutting processes without reclamping a workpiece. W

[3] Repairing Motor Section
Armature and Field can be replaced without disassembling Gear housing section.
[3]-1. Disassembling Motor Section
Remove Carbon brushes from the machine.
Motor housing complete can turn freely by separating four M5x80 pan head screws from the machine.
However, the last one is difficult to be unscrewed because the tensile force of Tension spring 20 affects it through Chain
bar holder and Rotor holder. Therefore, push Handle to counterclockwise direction as mentioned in Fig. 1 to remove the
last M5x80 pan head screw.
Next, Turning Motor housing complete clockwise as shown in Fig. 2 so that the tensile force of Tension spring 20 can be
removed.

[3]-2. Reassembling Motor Section
Perform the disassembling procedure in reverse of the assembling steps.
The reassembling work can be successfully performed even if Tension spring 20 shrinks to the original size.
Drive Spring pin 5-20 into the hole of Rotor holder's hook upward from the bottom so that the upper end protrudes by 4mm
for the stopper of Tension spring 20. Install Armature from Chain bar holder side. It is useful as a guide when Motor
housing complete is installed.
Hook one end of Tension spring 20 in the hole of Grip holder L as shown in Fig. 4 after inserting Motor housing section in
Rotor holder. Chain cover should be vertical against ground. And both Motor housing and Rotor holder should be paralleled
to the ground while pulling Tension spring 20 using Handle as described in Fig. 5. At this time, while pressing Motor
housing section with knee, tighten four M5x80 pan head screws. This is to prevent the Motor housing section from slipping
off.

To release the tensile force of Tension spring 20, Turn the Motor housing clockwise.
The tension spring 20 will return to the original size. Consequently, Motor housing
complete can be easily removed.
Pull out Chain bar holder to your side from the front of tool while turning it.
Insert Type 94 Field insert jig (Makita part No. 1R275) between Sprocket 4 and the
wall of Chain bar holder in order not to revolve Spindle fixed with the Sprocket 4

Remove Sprocket 4 from tool by hand. If it is stuck on the spindle firmly, use Gear extractor Large (Makita part No. 1R045).
Strike the reverse side of Chain bar holder using plastic hammer, so Gear housing can be separated from Chain bar holder.
The connecting parts of Chain bar holder and Gear housing are three Spring pins 6-24 only.
Remove gear section from Gear housing, and then tap the gear section on the table to separate Helical gear 47 from the
other components of the gear section.
[5] Disassembling Vice Element
Vice element can be pulled out only by loosening Lever 98 ass'y as illustrated in Fig. 7. If chips attach in the Compression
spring 48 and Compression spring 36, the chips make the clamp operation worse. Therefore, disassemble and clean them.
Loosen M6x35 Pan head screw to remove the Compression springs using cordless impact driver with phillips bit No.3 as
mentioned in Fig. 8 while holding Vice shoe so as not to jump by the reaction force of the Compression springs.

Note: The following information applies to the products including 16.5mm cutter chain as the standard accessory.
1) Fix an yellow colored Indication plate to Base complete with M4x8 pan head screw as shown in Fig. 13 after aligning
the front edge of the Indication plate with front end of 16.5mm cutter chain.
2) When aligning the center of + Countersunk head screw M6x12 with the bottom of Base complete, drive Stopper pole
into the Base complete by hand in order to adjust the height of Rotor holder at ZERO position on Stopper pole as
shown in Fig. 14. After positioning it, tighten M8 Hex. nut onto the hole of Base complete firmly using Wrench.
Note: Face the gauge of Stopper pole to outside before tihgtening M8 Hex. nut.
3) Align the left end of Scale plate with the left end of the cutter chain by resetting the scale plate on the Base complete.
