(2)To attach the tool (SDS max shank), insert it into the hole until it contacts the innermost end of the hole as illustrated in Fig. 2.

If you continue to turn the tool with slight pressure, you can feel a spot where there is a hitch. At that spot, pull the grip to the direction of an arrow mark and insert the tool all the way until it hits the innermost end.

Releasing the grip reverts the grip and secures the tool in place.

(3)Pull the tool to make sure it is locked completely.

(4)To remove the tool, fully pull the grip in the direction

of the arrow and pull out the tool.

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.

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.

Fig. 4

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.

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.

6.RCD

The use of a residual current device with a rated residual current of 30 mA or less at all times is recommended.

Fig. 5

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.
