Lubrication
002974
This tool requires no hourly or daily lubrication because it has a grease-
packed lubrication system. It should be relubricated after every 6 months of
operation. Send the complete tool to Makita Authorized or Factory Service
Center for this lubrication service. However, if circumstances require that you
should lubricate it by yourself, proceed as follows.
First, switch off and unplug the tool.
Remove the plate 50 using a screwdriver, then replenish with fresh grease
002975
(60 g). Use only Makita genuine hammer grease (optional accessory). Filling
with more than the specified amount of grease (approx. 60 g) can cause faulty
hammering action or tool failure. Fill only with the specified amount of grease.
Reinstall the plate 50 and secure with the screws.
To maintain product SAFETY and RELIABILITY, repairs, any other mainte-
nance or adjustment should be performed by Makita Authorized Service Cent-
ers, always using Makita replacement parts.
