OPERATING INSTRUCTIONS

Installing or removing bull point or other bits (cold chisel, etc.)

Important:

Always be sure that the tool is switched off and unplugged before installing or removing the bit.

For HM1200 (Fig. 1)

Pivot the tool retainer to the side. (If it is difficult to move the tool retainer with your thumbs, tap it with a hammer.) Insert the bit into the tool barrel as far as it will go. Return the tool retainer to its original position to secure the bit.

To remove the bit, follow the installation procedure in reverse.

For HM1200B & HM1200K (Fig. 2)

Pull out and turn the tool retainer 180 degrees (1/2 turn). Then insert the bit into the tool holder with the notched portion on the bit facing back toward the tool retainer. Then pull out and turn back the tool retainer 180 degrees to secure the bit. Try to pull the bit out of the tool holder to make sure the retained bit before use.

CAUTION:

Never use B-type shank bits. They can cause damage to the tool. (For HM1200B)

Side grip/Side handle (auxiliary handle)

For HM1200 (Standard type) (Fig. 3)

The side grip swings around to either side, allowing easy handling of the tool in any position. Loosen the side grip by turning it counterclockwise, swing it to the desired position and then tighten it by turning clockwise.

For HM1200 (European type), HM1200B & HM1200K (Fig. 4)

The side handle swings around 360° on the vertical as well as back and forth on the horizontal. Turn the clamp nut clockwise to secure the handle in the desired position.

Switch action (Fig. 5)

CAUTION:

Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

Do not tape, tie or otherwise secure the trigger in the “ON” position.

To start the tool, simply pull the trigger. Release the trig- ger to stop.

Chipping / Scaling / Demolition

Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Replacement of carbon brushes (Fig. 6 & 7)

Whenever carbon brushes must be replaced, they cut out the tool automatically. When this occurs, replace both carbon brushes at the same time. Use only identical car- bon brushes.

Lubrication (Fig. 8)

This tool requires no hourly or daily lubrication because it has a grease-packed lubrication system. Lubricate the tool every time the carbon brushes are replaced.

Run the tool for several minutes to warm it up. Switch off and unplug the tool. Remove the crank cap using a Mak- ita 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 (30 g). Use only Makita genuine grease (optional accessory). Filling with more than the specified amount of grease (approx. 30 g) 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. Do not tighten the crank cap excessively. It is made of resin and is subject to breakage.

To maintain product safety and reliability, repairs, mainte- nance or adjustment should be carried out by a Makita Authorized Service Centre.
