Hammer grease Lubrication 003236 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. Run the tool for several minutes to warm it up. Switch off and unplug the tool. 003244 Remove the crank cap using a Makita lock nut wrench 35 (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. Wipe out the old grease inside and replace with a fresh grease (90 g; 3 oz). Use only Makita genuine hammer grease (optional accessory). Filling with more than the specified amount of grease (approx. 90 g; 3 oz) can cause faulty hammering action or tool failure. Fill only with the specified amount of grease. Reinstall the crank cap and tighten with the lock nut wrench. 11
