Insert the bit into the tool. Turn the bit and push it in until 
it engages. 
If the bit cannot be pushed in, remove the bit. Pull the 
release cover down a couple of times. Then insert the 
bit again. Turn the bit and push it in until it engages. 
After installing, always make sure that the bit is securely 
held in place by trying to pull it out. 

Fig.14 

To remove the bit, pull the release cover down all the 
way and pull the bit out. 

Bit angle (when chipping, scaling or 
demolishing) 

Fig.15 

The bit can be secured at 24 different angles. To 
change the bit angle, rotate the change lever so that the 
pointer points to the

symbol. Turn the bit to the 

desired angle. 

Fig.16 

Rotate the change lever so that the pointer points to 
the

symbol. Then make sure that the bit is securely 

held in place by turning it slightly. 

Depth gauge 

Fig.17 

The depth gauge is convenient for drilling holes of 
uniform depth. 
Press and hold the lock button, and insert the depth 
gauge into the hex hole. 

Fig.18 

Make sure the toothed side of the depth gauge faces 
the marking. 
Adjust the depth gauge by moving it back and forth 
while pressing the lock button. After adjustment, release 
the lock button to lock the depth gauge. 

NOTE: 

• 

The depth gauge cannot be used at the position 
where the depth gauge strikes against the gear 
housing/motor housing. 

OPERATION 

CAUTION: 

• 

Make sure the work material is secured and not 
unstable. Flown object may cause personal injury. 

• 

Do not pull the tool out forcibly even the bit gets 
stuck. Loss of control may cause injury. 

Hammer drilling operation 

Fig.19 

Set the change lever to the

symbol. 

Position the bit at the desired location for the hole, then 
pull the switch trigger. 
 

Do not force the tool. Light pressure gives best results. 
Keep the tool in position and prevent it from slipping 
away from the hole. 
Do not apply more pressure when the hole becomes 
clogged with chips or particles. Instead, run the tool at 
an idle, then remove the bit partially from the hole. By 
repeating this several times, the hole will be cleaned out 
and you can continue drilling operation. 

CAUTION: 

• 

There is a tremendous and sudden twisting force 
exerted on the tool/bit at the time of hole break-
through, when the hole becomes clogged with 
chips and particles, or when striking reinforcing 
rods embedded in the concrete. Always use the 
side grip (auxiliary handle) and firmly hold the tool 
by both side grip and switch handle during 
operations, and maintain good balance and safe 
footing. Failure to do so may result in the loss of 
control of the tool and potentially severe injury. 

Blow-out bulb (optional accessory) 

Fig.20 

After drilling the hole, use the blow-out bulb to clean the 
dust out of the hole. 

Chipping/Scaling/Demolition 

Fig.21 

Set the change lever to the 

 or  

 symbol. 

Hold the tool firmly with both hands. Turn the tool on 
and apply slight pressure on the tool so that the tool 
does 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 attempting to perform inspection 
or maintenance. 

• 

Never use gasoline, benzine, thinner, alcohol or 
the like. Discoloration, deformation or cracks may 
result. 

Lubrication 

CAUTION: 

• 

This servicing should be performed by Makita 
Authorized Service Centers only. 

• 

Do not perform lubrication just after the operation, 
wait until the tool cools down. Otherwise skin burn 
may result. 

This tool requires no hourly or daily lubrication because 
it has a grease-packed lubrication system. However, it is 
necessary to replace grease and carbon brushes 
periodically for tool's long life.
