OPERATIONS
When using the saw in a hand held fashion a slow rocking mo-
tion will provide the best cutting action. Alternating pressure
from the front of the cut to the rear of the cut offers reliable
results.
The saw will cut slower when cutting through rebar and other
reinforced materials. Allow the saw to run at full speed and use
light pressure. Pushing hard on the tool only increases chain
wear and stretching force adding to wear and increasing the
cost per cut.
6.2.2
When cutting ensure that the water supply is sufficient for
the cut being made.
1.
Connect all fittings (Air, Hydraulic, Water).
2. Turn on power supply.
3. Turn on water valve on the saw.
4. Once water is running through the bar apply and hold full
throttle to begin cut.
5. Use full throttle for the entire cut. Feathering the throttle
makes the saw difficult to control.
6.2.3
SLOW CHAIN SPEED
Be sure the compressor is providing the correct air pressure, 90 psi,
and cubic feet per minute, 90 cfm. These are the minimum require-
ments; ideal performance can be achieved at higher volume.
6.2.4
POOR CUTTING PERFORMANCE
Diamonds may be “glazed over”. Make a few cuts in abrasive
material such as cinder block to expose diamonds. In the case of
the pipe cutting chain, the segment does not wear away. However,
the diamonds will wear away leaving a smooth surface.
6.2.5
PREMATURE CHAIN STRETCH
Not enough water pressure. The recommended water pressure is
20 psi. Do not force the chain. Extra force will cause the chain to
stretch faster.
6.2.6
CHAIN TENSIONER BREAKAGE
Side cover nuts are not tight enough.
6.2.7
WATER NOT FLOWING
Water hose is kinked, blockage in guide bar water ports, or water
supply is not turned on.
6.2.8
MOTOR DOES NOT START
Insufficient air supply. Check compressor and air hose, valves, and
air inlet screen for blockage.
6.3 MAINTENANCE
Only proper maintenance can ensure consistent saw performance,
reduction of wear, and thus, a reduction in operation costs and an
increase in service life.
6.3.1
Service life and performance of the chain saw are deter-
mined by:
1. Degree of air purity
2. Lubrication
3. Maintenance
6.3.2
SYSTEM CLEAN-UP
1.
Run saw, with water on, for 15 seconds out of cut to flush
slurry and/or debris from chain, bar, and drive.
2. Wash concrete slurry, cutting debris, and/or ductile shavings
from saw assembly.
3. Remove bar and chain. Flush out chain tensioner assembly
location with high water pressure, then lube with grease.
4.
Clean all air fittings on saw and compressor.
5.
When finished cleaning saw, spray entire saw, chain, bar, and
drive sprocket with a light weight penetrating oil (ie: WD40).
This will minimize rust and reduce build-up on saw assembly.
6.3.3 LUBRICATION
For every 50 hours of operation the motor will need to be greased.
There is a grease fitting on the motor. It will need 2 pumps of stan
-
dard bearing grease.
