the bottom part and out between the front wheels where the hook (2) is to be found.
SAFETY PRECAUTION WINCHING - SPOOLING
MOVING PART HAZARD
To Prevent Serious Injury And Property Damage:
• Do not operate winch before you have read
and u nderstood the operator’s manual.
• Stand clear of wire rope and bad during
operation.
• Keep others away.
• Always inspect the condition of the winch
and wire rope, before operating winch.
• Do not exceed winch’s rated capacity.
• Never touch wire rop e or hook while in
tension.
To Prevent Serious Injury:
• Keep hands clear of wire rope, hook and
fairlead opening during operation and when
spooling.
• Always use a rag or cord to hold hook when
spooling under no load.
• Wear heavy leather gloves wh en handling
wire rope.
• Never winch with less than 5 wraps of wire
rope around drum.

14.1 Pulling out wire rope – manual
The clutch knob, located on the winch housing Clutch for free spool
opposite the motor, controls the clutch position.
When th e clutch is in free spool, the gear train and
wire rope drum are uncoupled, allowing the drum
to rotate freely for pulling out the wire.
To prevent damage, always fully engage or fully
disengage the clutch knob.
WARNING
Do not disengage clutch if
winch is under load or
wire rope is in tension.
14.2 In and out spooling – automatic
The spooling switch is located on the winch motor.
When clutch above is engaged, the gear train is coupled to the wire rope drum, and power may
be transferred from t he winch motor.
When turning the spooling switch to the right or left the motor activates for automatic in - as well
as out spooling.
Operating problems:
Remember that the winch is operated by the 12 - v battery system. Long

15.0 Maintenance and inspection
For the safety of yourself and others, always keep the machine in good condition.
Missing and damaged parts have to be replaced or repaired immediately.
Never do maintenance the machine while the electricity is
connected!
It is very important to clean the machine after use because of the thick layer of concrete that will
be left on th e machine. This layer will keep for a long time, which in turn will cause a corrosive
attack. The layer may also prevent the machine from working properly.
Cleaning the electric motor is especially important since a layer of concrete reduces the motors
ai r- cooling ability, which may cause overheating, overload and failure.
Motor - loss of output
The motor has a maximum output limit. In addition to the
output required for the sawing, the total output is used for:
- Running the motor and the ball be aring friction,
- Friction in the V - belts, and
-Friction in the shaft bearing.
If the V- belt and/or shaft bearings are not properly adjusted,
this may cause a significant loss of output left for the
sawing. Therefore, keep these parts in good condition and
change shaft bearings when it shows signs of wear.
Control the V - belts
- In the beginning, V - belts must be checked after one day of
use, and if necessary tightened properly.
- Check the V - belts periodically. Loose V - belts will cause
wear and tear, and skidding causes loss of output for the
sawing spindle.
- If one V - belt breaks, change all of them. Missing V - belts
or uneven V -belt sets causes loss of output.
- When changing V - belts, make sure that the spindle, pulley
and the motor is adjusted perfec tly on the centre line. Non -
parallel V - belts cause wear and tear on the new V - belts.
