Lubrication (Fig. 8 & 9)
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 circum-
stances require that you should lubricate it by yourself,
proceed as follows.
• Run the tool for several minutes to warm it up. Switch
off and unplug the tool.
• Remove the crank cap using a hex wrench, then
replenish with fresh grease (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 crank cap securely with the hex wrench.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
