Operation; Maintenance - Makita UP100D Instruction Manual

OPERATION

CAUTION:
Always hold the tool firmly. And
keep firm footing.
CAUTION:
Do not put any of your body parts
near the shear blades during operation.
CAUTION:
Before use, inspect if the shear
blades, blade bolts or other parts are not worn or
damaged. Replace worn or damaged parts for safe
operation.
NOTICE:
If the shear blades are stuck in a branch
during operation, do not twist the tool. Release
the switch trigger and turn off the tool, and then
pull the shear blades straight out slowly from the
branch. Otherwise the shear blades may be damaged.
NOTICE:
In case you cut too thick branch or
something too hard, the overload protection works
and the tool stops. In this case, release the switch
trigger and turn off the tool, and then pull the shear
blades straight out slowly from the branch.
Using the holster
Pass the belt through the opening of the holster as
shown in the figure, and then put on the holster.
► Fig.19
Insert the tool into the holster. You can fix the tool with
the strap. Before inserting the tool into the holster, close
the upper shear blade by pulling the switch trigger more
than 3 seconds, and turn off the tool.

Pruning operation
► Fig.21
Maintain your proper footing and balance at all times
and cut branches one by one. The maximum thickness
of branches which can be cut with the tool is approxi-
mately 25 mm.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
CAUTION:
Wear safety gloves when handling
the shear blade. Otherwise it may result in personal
injury.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
Shear blade maintenance
NOTICE:
Failure to perform blade maintenance
may cause excessive blade friction and shorten
the operating time per battery charge.
Before the operation or once per hour during operation,
apply low-viscosity oil (machine oil, or spray-type lubri-
cating oil) to the shear blades.
► Fig.22
► Fig.23
Apply oil through the lubrication hole by pressing the
hole with the tip of the oil bottle.
► Fig.24: 1. Lubrication hole
After the operation, remove dust from the shear blades
with a wired brush, wipe them off with a cloth and then
apply low-viscosity oil (machine oil, or spray-type lubri-
cating oil) to the shear blades.

Adjustment for shear blades
clearance
NOTICE:
Adjust the clearance of shear blades
properly. Too loose clearance may result in dull
cut, and too tight blade clearance may result in
overload for the motor and short running time of
the tool.
Adjust the clearance of shear blades as follows:
1. Loosen the bolt with the hex wrench, and then
remove it.
► Fig.26: 1. Bolt
NOTICE:
Do not loosen the nut before loosening
the bolt. Otherwise, the nut may be damaged.
2. Loosen the nut with the box wrench, and then
tighten it manually.
► Fig.27: 1. Nut
NOTICE:
The recommended tightening torque is
approximately 0.5 N•m.
3. Attach the bolt to the tool and tighten it with the
hex wrench.
► Fig.28: 1. Bolt
4. Check that there is no gap between the upper
shear blade and lower shear blade.
► Fig.29
Check that the upper shear blade moves approximately
3 mm toward the lower shear blade.
► Fig.30: 1. Upper shear blade
Grinding the shear blades
NOTE: When grinding the shear blades, adding water
to the grinding stone will make the grinding smoother.
After the grinding, be sure to wipe off the shear
blades with a dry cloth.
Turn off the tool and remove the battery cartridge, and
remove the shear blades from the tool.
