(2)Tightening wood screws
Prior to tightening wood screws, make pilot holes suitable for them in the wooden board. Apply the bit to the screw head grooves and gently drive the
screws in the holes.
CAUTION
Exercise care in preparing a pilot hole suitable for the wood screw taking the hardness of the wood into consideration. Should the hole be excessively small or shallow, requiring much power to drive the screw into it, the thread of the wood screw may sometimes be damaged.
5. Using depth gauge (Fig. 14)
(1)Loosen the knob on the side handle, and insert the depth gauge into the mounting hole on the side handle.
(2)Adjust the depth gauge position according to the
depth of the hole and tighten the knob bolt securely.
6.How to use the drill bit (taper shank) and the taper shank adapter
(1)Mount the taper shank adapter to the rotary hammer. (Fig. 15)
(2)Mount the drill bit (taper shank) to the taper shank adapter. (Fig. 15)
(3)Turn the switch ON, and drill a hole to prescribed depth.
(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 hammer
supporting on the rest. (Fig. 16)
7.Switching between the “SAVE“ and the “POWER“ modes
The hammering force of the hammer can be increased or decreased to conform with intended usage, by operating the shift knob as per Fig. 17.
Adjust the force to match the usage intended.
(1)“SAVE“ mode ... decreased hammering force This can prevent thin drill bits which are less than
4.3mm in diameter, from being bent or broken.
(2)“POWER“ mode ... increased hammering force This can be used to speedily and efficiently drill
holes when the drill bits which are being used are greater than 4 mm in diameter.
This can be used to drill holes into wood or metal.
CAUTION
Do not drill holes in wood with the “SAVE“ mode. There is a likelihood that the motor will burn out
because it can easily lock up due to the low power.
8.About Remaining Battery Indicator
When pressing the remaining battery indicator switch, the remaining battery indicator lamp lights and the battery remaining power can be checked. (Fig. 18) When releasing your finger from the remaining battery indicator switch, the remaining battery indicator lamp goes off. The Table 5 shows the state of remaining battery indicator lamp and the battery remaining power.
Table 5
State of lamp Battery Remaining Power
The battery remaining power is enough.
The battery remaining power is a half.
The battery remaining power is nearly empty.
As the remaining battery indicator shows somewhat differently depending on ambient temperature and battery characteristics, read it as a reference.
NOTE:
Do not give a strong shock to the switch panel or break it.It may lead to a trouble.
To save the battery power consumption, the remaining battery indicator lamp lights while
pressing the remaining battery indicator switch.
9.How to use the LED light
Every time you press the light switch on the switch panel, the LED light lights or goes off. (Fig. 19)
To prevent the battery power consumption, turn
off the LED light frequently.
CAUTION
Do not expose directly your eye to the light by
looking into the light.
If your eye is continuously exposed to the light, your eye will be hurt.
NOTE:
To prevent the battery power consumption caused by forgetting to turn off the LED light, the light goes off automatically in about 15 minutes.
LUBRICATION
Low viscosity grease is applied to this rotary hammer so that it can be used for a long period without replacing the grease. Please contact the nearest service center for grease replacement when any grease is leaking form loosened screw.
Further use of the rotary hammer despite the grease shortage causes damage to reduce the service life.
CAUTION
