Safety and Precautions
For your safety, and the protection of the equipment, before using this machine, please make sure to read this manual carefully,
and strictly follow it for the process of transporting, commissioning, operating and troubleshooting.

1.1 Safety Guide
[1]: The operator must wear water-proof and insulating work shoes and gloves, and barefooted operation is prohibited to
prevent personal casualty from electric shock.
[2]: The external connecting wire must be more than 4m2 and must be grounded to prevent electric shock.
[3]: Before using the equipment, you must check whether the power wire is damaged or aging. If so, immediately replace
the power wire to prevent the equipment from short circuit and electric leakage.
[4]: The operator on the machine is prohibited from preventing equipment shut-down for over-load or personal casualty
for electric leakage. Don’t put the equipment, the power and the socket into water or over-humid environment for
preventing the equipment damage from the short circuit.
[5]: When conducting wet grinding, waterproof protection should be conducted for the water tank, inverter and control
panel for preventing the equipment non-operation or personal casualty from equipment short circuit or electric leakage.
[6]: When using the equipment, don’t roll on the electric wire to prevent potential safety risk from electric wire damage.
[7]: When using the equipment, don’t insert the plug with wet hands for preventing injuries and deaths from electric
shock.
1.2 Precautions
[1]: After dry grinding and wet grinding treatment, completely clean the bottom part of the equipment to increase the
service life.
[2]: When conducting dry grinding with the equipment, please connect the vacuum cleaner, to ensure there is dust-free
operation, decrease the inverter load and guarantee the equipment is running normal.
[3]: In the process of replacing tooling and transporting, please be sure to put down the equipment gently for preventing
the strike and oil leakage of the gear box from the improper operation (If one person can’t carry the equipment easily in
the operation process, please look for other people to assist).
[4]: In a certain range of output frequency, the frequency inverter may produce the resonance which will cause the
equipment to stop working, under such a circumstance, please avoid the resonant frequency operation.
[5]: When conducting operation on the floor with a large difference of level, please be sure to grind from the higher to the
lower to prevent damage to the grinding plate and gear box from oversize difference of floor level.
[6]: Regularly check the grinding plate, if you find any loose screws on the grinding plate, tighten and maintain.

Operation Instruction
3.1 Equipment Operation Method
3.1.1 Equipment Operation Preparation
[1]: Prior to starting, check whether the power switch is in the off state to ensure the safety.
[2]: First adjust the handle in the line-style, and then hold the handle and with one foot stepping on the step bar and press
downwardly; after the equipment is fixed on the ground, check whether the external parts are complete, whether there is
any wrong installation of tools, neglected installation and loose parts. Immediately solve the problem if finding these issues.
[3]: After checking, press the equipment down until the chassis touch the ground, and lay it flat.
[4]: Apply grinding tooling onto the equipment, and the basic steps on the following page:
(1) As shown in Figure 2-1, the equipment chassis is loaded with a polishing plate
(2) Place desired tooling on machine utilizing the magnetic plates.
(3) After loading, check whether the parts are complete once again.
(4) Install or tighten the handle, clockwise rotate the black rotary handle to the tightest state. Rotate in the reverse
direction when dismounting the handle as shown in Figure 3.
