Description Trimmer
CONCEPTION AND MAIN APPLICATIONS
Unlike the conventional model, wherein the
bit is directly mounted on the motor shaft,
this offset-type trimmer can be driven by
the belt, wherein the bit shaft is mounted
separately from the motor shaft and the base
215mm
shape near the bit is arranged in triangle
(angle: 90"), thereby enabling the process
close to the wall and corner faces. 100mm

Features And Benefits
(1) The offset model allows to process even nearest to the wall and corner face. The max. approaching size between
wall face and bit center is 18.5 mm.
(2) The fine grip(the grip dia. : 65 mm) enables easy operation.
(3) Since the belt-driven system will relieve the cutting impact through absorbing into the belt, the endurance
capacity of the armature can be improved further than the conventional model.
(4) Since the base mounting bolt is fastened by the hexagon rod wrench, the base can be securely fixed.
Repair
(1) Replacing of poly-V-belt
Proceed in the following steps.
1.Use the hexagon rod spanner 6 to remove the hexagon holed bolt M8x11 for mounting the base.
2.Remove the base from the body.
3.Use the plus screw driver to remove the pan head screw M4x14 for mounting the belt cover to remove the belt
cover.
4.Use the -screw driver to twist the poly-V-belt to outside, set the spanner 10 on the cracked two-face width of
the drive shaft, shift the poly-V-belt to outside one by one thread while turning the spanner 10 to remove the
poly-V-belt.
5. After assembling the new poly-V-belt on all the teeth of V-pulley-3-19 of the armature assembly, set the
spanner 10 on the cracked two-face width of the drive shaft, engage the poly-V-belt with the V-pulley-3-23 little
by little while turning the spanner 10 in a way pushing the side face of the wrench 10 against the poly-V-belt.
(2) Replacing of the armature
After V-belt has been replaced in the orders of 1 to 4 for replacing the poly-V-belt,
6.Use the -screw driver to remove the holder cap of the carbon brush holder and then remove the left/right
carbon brushes.
7. Remove the three pan head screws M4x40 holding the housing.
8. Use the resin hammer to slightly hammer the drive shaft mounting portion on the motor housing to
disassemble the housing and then remove the armature.
9. Insert the V-pulley-3-19 of armature between the vice while protecting the armature with the copper plate etc.,
turn left the steel plate of the armature by hands to remove the V-pulley-3-19. For assembling, proceed in the
reverse orders against said disassembling.
(3) When the base depth position adjusting motion became heavy,
If dust has been entered between the guide pin of the base and the hole of bearing box for housing the guide pin
during operation, the base motion may become heavy sometimes. In this case remove the base, clean the dust
and then apply the oil into their engagement.
(4) Endurance capacity of the poly-V-belt
It may vary depending on the using conditions, but it is normally 140-hr when used in the rated load. If the poly-
V-belt may be partly damaged, the transmission capacity can be deteriorated. Replace the belt in this case.
(5) Necessary tools
In addition to the normally attached tools, the plus screw driver, minus screw driver, resin hammer and vice are
required.
