8. LUBRICATION MACHINE (See Fig. H)
The gearbox is lubricated with grease. Refilling is
required when the hammer efficiency is low. Open the
cover using the
key provided and add general purpose lithium based
grease.
CAUTION: Keep the container of grease away from
children.
9. SAFETY CLUTCH PROTECTION
This tool will generate high forces when use. Always hold
the tool with both hands and adopt a secure posture.
If the drill bit or chisel becomes jammed in the
workpiece, the clutch will activate stopping the tool
spindle. This is normal.
Switch the machine off, loosen and remove the drill bit
or chisel from the work piece.
CAUTION:
Switching the machine on with the drill bit or chisel
jammed in the work piece will generate high reaction
torque and can result in injury.
10. FITTING BITS OR CHUCK (See Fig. I1)
Clean the bit shank and apply grease before installing
the bit. Hold the rotary grip, pull back the lock sleeve
and insert the bits or chuck into the bit holder. Turn
the bit and push it in until a resistance is felt. The shaft
drops completely into the bit holder. Once you are
satisfied that it has been seated, release the black lock
sleeve. This would lock the bits or chuck into position.
After installing, always make sure that the tool or chuck
is securely held in the bit holder by trying to pull it out.
If the bits or chuck is not located well, repeat the
operation again.
11. REMOVE BITS OR CHUCK (See Fig. I2)
To remove the bits or chuck, pull back the locking
sleeve, hold and pull the bits or chuck out.
NOTE: The bits or chuck are gripped firmly by the
shank and can not be removed once locked in position.
