(Note: Do not open the water valve when working on the side and top position)
6. Feed should be slow at first. Do not exert too much in case of overload.
7. If the motor suddenly stops or gets stuck due to a fault, the drill control switch 9
must be turned off immediately (Note: do not turn off the electromagnet switch 5).
After continuous use for 2-3 hours, you need to rest to prevent the
electromagnetic seat from burning out due to overheating.
8. When the carbon brush is worn out, please replace it in time (both of them
should be replaced at the same time).
COOLING DOWN AND ADJUSTMENT OF THE TRACK
1. Fix B1 at B, then connect B2 to B1 and C.
2. Turn the joystick to determine whether the tightness of the track meets the
drilling requirements. If the tightness is not ideal, you can adjust it with the open
wrench and the hex wrench in the attachment.
a) Loosen the hex nut at place A with an open wrench.
b) Use the hex wrench to adjust the set screw at A and turn the joystick 7
simultaneously to feel whether the tightness of the track reaches the ideal state of
drilling.
c) After adjustment, tighten the hex nut at A with the open-end wrench.
Note: The tightness of the track has been adjusted before leaving the factory. If
there has been no strong vibration, fall, and other conditions, please do not adjust.
