5. Regulating the number of rotations and hammering
(Fig. 3)
This Rotary Hammer is equipped with a built-in
electronic control circuit that can adjust and regulate
the number of rotations and times of hammering.
This Rotary Hammer can be used by adjusting the
dial, depending upon the contents of operation,
such as boring holes into fragile materials, chipping,
centering, etc.
The scale ‘1’ of the dial is designed for a minimum
speed with the number of 120 rotations per minute
and 1250 times of blow per minute. The scale ‘6’
is designed for a maximum speed with the number
of 240 rotations per minute and 2500 times of blow
per minute.
CAUTION:
Do not adjust the dial during operation. Doing so
can result in injury because the Rotary Hammer
must be held by only one hand, disabling the steady
control of the Rotary Hammer.
HOW TO USE THE ROTARY HAMMER
1. How to drill holes (Fig. 4)
(1) Pull the switch trigger after applying the drill bit
tip to the drilling position.
(2) It is unnecessary to forcibly press the rotary hammer
main body. It is sufficient to slightly press the rotary
hammer to an extent that shavings are freely
discharged.
CAUTION:
Although this machine is equipped with a safety
clutch, if the drill bit becomes bound in concrete
or other material, the resultant stoppage of the drill
bit could cause the machine body to turn in reaction.
Ensure that the main handle and side handle are
gripped firmly during operation.
2. How to chisel or crush (Fig. 5)
By applying the drill bit tip to the chiseling or
crushing position, operate the rotary hammer by
utilizing its empty weight.
Forcible pressing or thrusting is unnecessary.
3. When drilling at “rotation + hammering”:
CAUTION:
If you switch the selector lever during motor rotation,
the tool can start to rotate abruptly, resulting in
unexpected accidents. Be sure to switch the selector
lever when the motor is at a complete stop.
(1) Switching to “rotation + hammering”
(a) Push the button, release lock and turn the selector
lever clockwise.
(b) Align ▲ of the selector lever and
of the lever
holder as illustrated in Fig. 6.
(c) Release the button to lock the selector lever.
NOTE:
Turn the selector lever (do not push the button) to
check if it is completely locked and make sure that
it does not turn.
4. When chipping and chiseling at “hammering”:
CAUTION:
䡬 If the selector lever is switched during motor rotation,
the tool can start to rotate abruptly, resulting in
unexpected accidents. Make sure to switch the
selector lever when the motor is at a complete stop.
䡬 If the bull point or cold chisel is used at the position
of ”rotation + hammering”, the tool can start to
rotate, resulting in unexpected accidents. Make
sure that they are used at the position of
”hammering”.
(1) Switching to ”hammering”
(a) Push the button, release lock and turn the selector
lever counterclockwise.
(b) Align ▲ of the selector lever and
of the lever
holder as illustrated in Fig. 7.
(c) Release the button to lock the selector lever.
NOTE:
Turn the selector lever (do not push the button) to
check if it is completely locked and make sure that
it does not turn.
(2) When fixing working positions of tools such as cold
chisel, etc.,
(a) Push the button, release lock and turn the selector
lever.
Align ▲ of the selector lever and
of the lever
holder as illustrated in Fig. 8.
(b) Release the button to lock the selector lever.
(c) Turn the grip as illustrated in Fig. 9 and fix the
tool to the desired working direction.
(d) Switch the selector lever to “hammering”
according to the procedures mentioned in the
above item (1) and secure the position of the tool.
5. Install the stopper (Fig. 10)
(1) Loosen the side handle and insert the straight portion
of the stopper into the handle bolt hole.
(2) Move the stopper to the specified position and
rotate the grip of the side handle clockwise to fix
the stopper.
6. Warming up (Fig. 11)
The grease lubrication system in this unit may
require warming up in cold regions.
Position the end of the bit so makes contact with
the concrete, turn on the switch and perform the
warming up operation. Make sure that a hitting
sound is produced and then use the unit.
CAUTION:
When the warming up operation is performed, hold
the side handle and the main body securely with
both hands to maintain a secure grip and be careful
not to twist your body by the jammed drill bit.
DRILLING AND DRIVING-IN OPERATIONS FOR
ANCHORS
1. When a taper shank adapter is used. (Fig. 12)
(1) Install drill bit with taper shank in the taper shank
adapter.
(2) Turn the power on and drill a base hole to the depth
sounded by indicating groove on the drill bit.
(3) After cleaning out dust with a syringe, attach the
plug to the anchor tip and drive in the anchor with
a manual hammer.
(4) To remove the drill bit (taper shank), insert the
cotter into the slot of the taper shank adapter and
strike the head of the cotter with a manual hammer
supporting on a rest. (Fig. 13)
