Cayken 913 - Common Fault and the Method of Removing

8
L is the files of low speed, H is high speed files, M is the files of middling speed
( 3 files types), graphic representation is the files of low speed, spin along hour
hand if by the files of low speed, turning high speed files knob, otherwise
counter-clockwise.
COMMON FAULT AND THE METHOD OF REMOVING
Fault
Reason
The method of removing
Generator
does
not
turn
Power source is obstructed ,
or contacts to loosen to fall
Carbon brush blocks ,
take off open commutator
After the protector movement of
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
by thin bits
Rotational speed is too high
It is slippery 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
The leather or broken bits piece of
reinforcing bar blocks , is geting into
core between bit or between bit and
hole wall, frame fixes , is not firm , it is
exceptional to produce displacement
frame pillar and the gap of sliding
sleeve.
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.
Drill hole
is too
slow
Bit
blocks
Bit wall
wear is
rapid
Water set
leakage
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
Main shaft not just
Bit not just
Reinforcing bar or thin bits can not
remove hole outside
The skeleton wear or ageing of sealing
ring
Repair or change main shaft
Change bit
Improvement current, take out bit , clean hole
Change skeleton sealing ring
