Lubricate the sliding surfaces of Front base and Main frame with an appropriate amount of lubricant such as
Machine oil #120.
[3] Disassembling/Assembling
[1] Necessary Repairing Tools
Bearing Setting Plate (No.1R033) ......... For press-fitting ball bearing
Bearing Extractor (1R269)..................... For removing ball bearing
<1> Replacing Poly V-Belt
Disassembling
1. Remove Belt cover.
2. When replacing parts such as armature or drum, you will
probably reuse the Poly V-belt once removed.
In this case, remove the belt by turning V pulley 4-37
in the direction of the arrow while lifting up the belt with
a Lock nut wrench of a Makita grinder. (Fig. 1)
When you replace the Poly V-belt with a brand-new one,
remove simply by cutting the worn belt with cutting pliers.
<2> Replacing Armature and Drum
Disassembling
1. Remove Chip cover, and then remove Brush holder caps carbon brushes.
2. Remove six M4x25 Pan head screws fastening Bracket complete to Main frame complete as illustrated to left
in Fig. 3.
3. Holding the handle, turn the tool so that it stands on Base. With plastic or wooden hammer, hit Main frame
complete alternately at the two portions designated by the black arrow as illustrated to right in Fig. 3.
The assembly of Bracket complete, Drum and Armature will then be removed from Main frame complete.
4. Remove V pulleys from Bracket complete as described below;
Hold Drum or Armature assembly with rags. And then using a wrench 13, remove V pulley 4-37 (right-handed)
by turning it counterclockwise, and V pulley 4-20L (left-handed) by turning it clockwise.
Assembling
1. Remove Belt cover.
2. Install Poly V-belt 4-241 securely on V pulley 4-20L,
and then install the belt on V-pulley 4-37 while turning
V pulley 4-37 in the direction of the arrow. (Fig. 2)
Note: It will help you easily install Poly V-belt 4-241
to follow the instruction described below;
In order not to allow the belt to be out of the
V-grooves on the two V pulleys, while turning
V pulley 4-37, press the half of the belt opposite
to the other half being installed as illustrated
in Fig. 2.
Always follow the instructions of the SAFETY RULES and OPERATING INSTRUCTIONS described in the
instruction manual. Also refer to the instruction manual for how to replace and adjust the planer blades.
CAUTION: Before starting repair, be sure to unplug the tool and remove planer blades from the tool for safety.

[3] Planing Depth Adjustment
<2> Replacing Armature and Drum
Disassembling
5. Remove Ball bearings 6000ZZ and 608ZZ from Drum using Bearing extractor (No.1R269).
Between Drum and Ball bearing 608ZZ, there is no space for insertion of the jaw of the bearing extractor.
When removing Ball bearing 608ZZ, therefore, be sure to use a proper adjustable wrench to securely hold the
jaws of the bearing extractor so that the jaws cannot spread and slip off the ball bearing. (Fig. 4)
Note: Be careful not to cut yourself on the sharp edges on the front faces of Drum.
Scale label on knob 42 does not indicate correct planing depth after replacement of any one of the following parts:
Front base, Base, Main frame complete, Knob 42
In this case, be sure to replace Scale label and do planing depth adjustment as described below.
1. Remove Scale label from Knob 42, and then assemble Base and parts of Front base section to the tool.
2. Put the tool on a completely flat surface such as the table of stationary planers or the turn table of LS-series models.
(If these tools are not available, use a stainless steel scale instead.)
And then turn Knob 42 so that the height of Base is completely aligned with that of Front base.
3. Install Scale label on Knob 42 so that the line of 0mm on Scale label is aligned with the apex of the triangle mark
on Main frame complete as illustrated in Fig. 6.

Assembling
1. Do the reverse of disassembling procedure.
2. When installing Ball bearings 608ZZ and 6000ZZ on Drum,
use arbor press and Bearing setting plate (No.1R033) as
illustrated in Fig. 5.
