Changing the tool (SDS-MAX) (4)
Note
: It is a characteristic of the system that product a radial eccentricity when the machine is running at no-
load speed. This does not affect the accuracy of the drilled hole as the bit is automatically centered during
drilling.
The tool holder is maintenance-free. The dust cap prevents drilling dust from entering the machine during
operation.
Inserting tools
Clean and lightly grease tool shank before
inserting (A.2)
Twist the tool into the holder and push it in until it engages. The tool shank locks in position automatically.
Pull the tool to check if it is locked correctly.
Removing the tool (A.2)
Push back the locking sleeve of the tool holder and remove the tool.
HOW TO USE THE HAMMER
1. After placing the tip of in the base hole. Switch ON. In some cases. It is necessary to punch the up of the
bit against the crushing position forcibly in order to begin the striking stokes. This is not due to malfunction
of the tool. It means that the safe guard mechanism against no-load striking is working.
2. By utilizing the weight of the machine and by firmly holding the hammer with both hands, one can
effectively control the subsequent recoil motion. Proceed at a moderate mark-rate, the use of too much force
will impair efficiency.
Caution:
Sometimes the tool does not begin the striking stroke even when the motor rotates because the oil
has become thick. If the tool is used at low temperatures or if it is used running in for five minutes in order
too warm it up.
OIL FEEDING (4)
Caution:
Prior to oil feeding, always disconnect the plug from the power supply receptacle. Since an oil
chamber is built in this Electric Hammer, it can be used for approximately 20days without supplying
lubricating oil, assuming that the hammer is used continuously 3~4 hours daily.
Feeding oil into the oil tank as described below before using this hammer.
1. Just before no oil is visible in the oil gauge windows when the device is held upright feed oil to warm it up.
2. Before feeding oil, use the wrench to remove the oil gauge. Be careful not to lose the rubber packing
attached below the oil gauge.
3. Check the oil level once daily, confirming that oil is filled.
4. After feeding oil, securely clamp the oil gauge.
MAINTENANCE AND INSPECTION
1.
Inspecting the tool
Since use of a dull tool will cause motor malfunctioning and degraded efficiently, when it or replace with a
