Operation; Maintenance; Optional Accessories - Makita BCG140 Instruction Manual

Insert the film type pack into the holder. (Fig. 17)
Attach the rubber ring, the nozzle and the holder cap.
Make sure holder cap is tightened firmly.
Push the rod gently until the piston touches the bottom of
the film type pack.
NOTE:
• Always check the film type pack for puncture or
damage before installing. Do not use damaged pack,
otherwise the tool may be damaged.
Direct filling
NOTICE:
• Make sure the piston C is attached to the rod. Do not
use other type of piston for direct filling.
• Direct filling can only be performed with the long holder
(600 ml).
Remove the holder cap, the nozzle and the rubber ring
from the holder.
Make sure the rod handle is placed at the most front
position.
Dip the mouth of the holder into the caulking material.
Pull the rod handle slowly until required amount of
caulking material is filled in the holder.
Attach the rubber ring, the nozzle and the holder cap.
Make sure holder cap is tightened firmly.
NOTICE:
• Clean the holder with appropriate solvent after every
day's work. Otherwise adhered caulking material may
cause tool breakage.

OPERATION

CAUTION:
• Do not touch the rod during operation. Otherwise your
finger may be pinched between the rod and the
housing of the tool.
• Always wear goggles during operation.
NOTICE:
• Do not cover vents, or it may cause overheating and
damage to the tool.
• If you can not pull out the rod, turn the speed adjusting
dial to 1, and pull the switch trigger for a moment, and
try to pull the rod out after the motor stopped. If the rod
is still clogged, perform the same action until the rod is
able to move.
Cut off the tip of the nozzle suitable for individual
operation. Be careful how much you cut the nozzle. The
diameter of the nozzle affects the amount of caulking
material dispensed.
Pull the trigger to dispense caulking material.
The amount of the caulking material dispensed is
determined by the trigger, the speed adjusting dial, the
diameter of the nozzle opening, caulking material type,
and temperature.
It is recommended that the speed adjusting dial is set to
"1" and pull the trigger slowly at the first time to test how
much amount of caulking material is dispensed.
When the rod reaches front end, the motor starts idling.
Replace the caulking material when it happens.
NOTE:
If the caulking material is not dispensed, check the
following items:
8
• Nozzle tip is not cut adequately. Cut the nozzle tip
suitable for individual operation.
• Hardened material gets clogged in the nozzle. Remove
the hardened material.
• The cartridge is damaged. Replace the cartridge.
• Caulking material is stiff. Warm the material until it
becomes soft.
• The wrong piston is used. Use appropriate piston.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance except for the
following troubleshooting related to the light.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
• Clean the holder and the rod after every day's work.
Keep them free from the adhesive material. Remove
the caulking material before it hardens. Remained
adhesive material may cause breakage of the tool.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.
