Chipping/Chiseling (Fig. B)
uWhen the cutting / stripping / removing opera- tion is conducted, please put the operation modes selector (3) to position 
, the drilling bit, cold chisel and scaling chisel etc. should be properly used.
Warning! Do not rotate the knob when the power tool is rotating under the load, otherwise it will be damaged.
Hammer drilling (Fig. B)
uWhen using the hammer driller to drill holes on the masonry and concrete surfaces, the opera- tion mode selector (3) should be set to position 
.
uThe drilling bit should be aligned to the drilling position, and then press the switch button to achieve the best effect. Keep the power tool be positioned correctly, prevent it from deviating the hole.
uWhen the fragments plug the borehole or powders, please do not apply further pressure, and make the tool rotate in an idling state, then gradually take out the drilling bit from the hole. Repeat the said steps for several times, the plugged hole can be clean, and then resume the normal drilling.
Warning! When the drilling bit begins to break down the reinforced concrete or hit the steel bar inside the concrete, the power tool may have dangerous reaction force. Please always keep balance, stable posture and tightly grip the tool, to prevent from generating the dangerous reaction force. When the concrete is chiseled, the distance between the two points of one chiseling shall not be too much away from the edge, which shall be about 8cm or so, define the distance through find- ing the cracking strength of the concrete.
Overload coupling device
If the drilling bit is clamped or hooked up, the driv- ing force transmitted to the drill shaft will be cut off. A huge force will occur, so two hands must tightly grip the power tool when it is in operation, and ensure that the operator is standing in a stable and fixed position.
Select the depth of holes to be drilled (Fig. C)
A depth gauge is an easy to use ruler to ensure that the drilling depth is consistent. Unlock the side handle, adjust the depth gauge according to the required depth, and then tighten the side handle.
uUnfasten the side handle (6) by turning counter- clockwise the grip.
uSet the depth stop (7) to the desired position.
The maximum depth of the drilled hole shall equal to the distance between the tip of drilling bit and the front end of the depth stop.
uTighten the side handle by turning the grip clockwise.
Switch on and off
Warning! Before inserting the plug, please con- firm whether the switch can trigger freely or not, whether it can return to the original position after releasing.
uPress the switch button (1), the power tool can be started immediately.
uRelease the button (1), the tool stops rotating.
