Lubrication
006205
This tool requires no hourly or daily lubrication because it has a grease-
2
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 cap using a wrench 23, then replenish with fresh grease (60 g).
006206
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 cap and secure with the wrench.
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.
