Maintenance; Optional Accessories - Makita HR2010 Instruction Manual

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon brushes
should be replaced. Keep the carbon brushes clean and
free to slip in the holders. Both carbon brushes should be
replaced at the same time. Use only identical carbon
brushes. (Fig. 7)
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps. (Fig. 8)
Lubrication
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. Lubricate the
tool every time the carbon brushes are replaced.
Run the tool for several minutes to warm it up. Switch off
and unplug the tool.
Remove the crank cap using a Makita lock nut wrench
(optional accessory). Rest the tool on the table with the bit
end pointing upwards. This will allow the old grease to
collect inside the crank housing. (Fig. 9)
Wipe out the old grease inside and replace with a fresh
grease (30 g). Use only Makita genuine hammer grease
(optional accessory). Filling with more than the specified
amount of grease (approx. 30 g) can cause faulty
hammering action or tool failure. Fill only with the
specified amount of grease. (Fig. 10)
Reinstall the crank cap and tighten with the lock nut
wrench.
CAUTION:
• Do not tighten the crank cap excessively. It is made of
resin and is subject to breakage.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
