PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

1. Power switch

Ensure that the power switch is in the OFF position. If the plug is connected to a power receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

1. Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

1. How to install tool

NOTE:

For tools such as a bull point and a cold chisel, use only Hitachi genuine parts.

(1) Clean, then smear the tool shank with the grease provided in the green tube (Fig. 1).

(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.

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.

(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)

USING DRILL CHUCK, CHUCK ADAPTER

Note that this machine can be used at "rotation only" if separately sold parts such as drill chuck and chuck adapter are attached. Use it with the selector lever positioned at "rotation + hammering".

CAUTION:

During operation, be sure to grip the handle and the side handle firmly to prevent your body from swaying.

(1) Switching to "rotation + hammering"

For switching to "rotation + hammering", follow the same procedures mentioned in [3. When drilling at "rotation + hammering"].

(2) Attaching chuck adapter to drill chuck (Fig. 14)

(a) Attach the chuck adapter to the drill chuck.

(b) The SDS max shank of the chuck adapter is equivalent to the drill bit. Therefore, follow the same procedure as [How to install tool] for attaching and detaching.

(3) Drilling

(a) Even if you apply more-than-required pressure to the machine body, drilling can never be performed as quickly as you expect. Applying more force or pressure to the machine body than what is needed, on the contrary, damages the drill tip, resulting in the declined working efficiency and shortened life of this machine.

(b) A drill can snap sometimes when drilling is almost finished. It is important to relax your thrusting pressure when drilling is nearing the end.

HOW TO HANDLE A CORE BIT

When a core bit is used, large diameter holes and blind holes can be drilled. In this case, use optional accessories for core bits (such as a center pin and core bit shank) for more efficient operation.

1. Mounting

CAUTION:

Prior to mounting a core bit, always disconnect the plug from the power supply receptacle.

(1) Mount the core bit on the core bit shank. (Fig. 15) Before that, feed oil to the screw portion of core bit shank for easy dismounting.

(2) Mount the core bit shank on the main body in the same manner as in mounting the drill bit and the bull point. (Fig. 16)

(3) Insert the center pin into the guide plate until it reaches the extremity.

(4) Fit in the guide plate by aligning its concaved portion with the core bit tip. When the position of the concave is shifted by turning the guide plate right or left, the guide plate never slips off even when the drill is used in a downward direction. (Fig. 17)

2. Drilling holes

(1) Insert the plug into a receptacle.

(2) A spring is built in the center pin. By straightly and gently pressing it to the wall or floor surface, the entire surface of the core bit tip attains contact to start the hole drilling job. (Fig. 18)

(3) When the hole depth reaches approximately 5 mm, the hole position can be determined. Then remove the center pin and guide plate from the core bit and continue the hole drilling job.

CAUTION:

When removing the center pin and guide plate, always disconnect the plug from the receptacle.

3. How to dismount the core bit

○By holding the rotary hammer (with the core bit inserted) in an upward position, drive the rotary hammer to repeat impact operation two or three times, whereby the screw is loosened and the rotary hammer becomes ready for disassembly. (Fig. 19)

○Remove the core bit shank from the rotary hammer, hold the core bit with one hand, and strongly strike the head of the SDS max shank portion of the core bit shank with a manual hammer two or three times, whereby the round head screw is loosened and the rotary hammer is ready for disassembly. (Fig. 20)
