take off open commutator

After the protector movement of

not

leakage of electricity, do not reset

The protector damage of

leakage of electricity

Bit life has arrived

Feed pressure is too low

Bit knife first surface is pasted

Drill hole

by thin bits

is too

Rotational speed is too high

slow

It is slipper y to cut thick reinforcing

bar to hit

In processing hole, amass bits

Current does not be obeied , leakage

or have no reflux

Bit sharp degree reduces

ring

The method of removing

Resume power source , inspect all joints and tighten

New installation carbon brush

Press reset button to start generator again

Change the protector of leakage of electricity

Change bit

Increase feed pressure

Clean bit, increase hydraulic pressure

Switch the files position of low speed

Feed pressure reduces is little after,will cross reinforcing

bar increase pressure again

Put in order hole bottom. Pressurization

Inspect into the valve of water polo , inspect current

Using fire-resistant brick or emery wheel open edge again

Stop machine , turn bit around spanner, or pull out bit

to knock broken get into heart to fix the frame

adjustment gap of sliding sleeve again.

Repair or change main shaft

Change bit

Improvement current, take out bit , clean hole

MAINTENANCE AND REPAIR

ATTENTION: You must remove the main plug from the supply socket before beginning

any maintenance or repair work.

Clean the machine with a dry or moist cheaning-rag and not with a jet of water. Make sure

that no water gets into the motor or the switch box. Ensure that the ventilation slots are always

clean. Clean and greases the tool thread , too.

Oil bath gear

The gear oil should be changed after the first 300 hours of operation. Ensure that this work

is carried out in a specialist workshop, or proceed as follow: Clamp the machine vertically in the

vice. Remove the three hexagon socket screws. Take off motor and inter-mediate cover. Change

gear oil-use only original oil. The filling quantity is 300-310ml.To reassemble, proceed vice vesa

and ensure that the shim ring is on the front shaft.

ATTENTION: if gear oil escapes, stop the machine immediately. Leakage of oil damages

the gear. Water connection

If water escapes from the overflow hole on the water connection ring, the rotary shaft seals

must be replace immediately. This should only be done in an authorized specialist workshop.

Carbon brushes

The carbon brushes should be examined for wear after about 300 hours in operation, and

replaced if necessary. As with all other work on the motor, this should only be carried out by an

electrician.
