002954 Use a screwdriver to remove the brush holder caps. Take out 1 2 the worn carbon brushes, insert the new ones and secure the brush holder caps. 1. Screwdriver 2. Brush holder cap 1. Screws 1 002967 1 002968 2 Lubrication 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. Loosen the six screws and remove the handle. Remove the crank cap using a socket wrench. Rest the tool on the table with the bit end pointing upwards. This will allow the old grease to collect inside the crank housing. 1. Socket wrench 2. Crank cap 1 1. Hammer grease 10 002969 Wipe out the old grease inside and replace with a fresh grease (30 g; 1 oz). Use only Makita genuine hammer grease (optional accessory). Filling with more than the specified amount of grease (approx. 30 g; 1 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 socket wrench. CAUTION: • Do not tighten the crank cap excessively. It is made of resin and is subject to breakage. • Be careful not to damage the terminals or lead wires especially when wiping out the old grease or installing the handle.
