SAFETY
Chain breakage can result in high-speed ejection of parts, which can result in death or
serious personal injury to operators or bystanders. The items listed below are critical to
minimizing the risk of chain breakage and injury.
• DO NOT operate a diamond chain saw with damaged, modied, broken, or missing
side cover, bottom guard ap. The side cover, bottom guard, and guard ap provide
protection against contact with moving parts, ejected debris, broken chain, thrown
water and concrete slurry.
• DO NOT operate a saw with loose, missing, damaged, or improperly repaired parts.
• DO NOT install or run the chain backwards. The bumper must lead the segment into
the cut. (Applies to concrete chains only.)

• Always turn the compressor source OFF, and ensure air lines are decompressed
and disconnect the chain saw from the air hose (even when the compressor is
OFF when performing maintenance on the saw including chain tensioning.
• Never use equipment that is not functioning properly. Have the saw repaired by a
qualied service personnel.
• Diamond chains require a minimum water pressure of 20 PSI. Insufcient
water supply may result in excessive wear to the chain which can lead to loss of
strength and chain breakage.
• Never start a diamond chain saw unless the bar, chain, and side cover are
properly installed.
General Safety Precautions
• Always wear protective clothing, including hard hat, eye protection, hearing
protection, and gloves.
• Avoid loose tting clothing.
• Perform safety checks before starting each day.
• Always operate tool with solid footing and with both hands on the saw.
• Remove or control slurry to prevent slippery conditions while cutting.
• Be sure there are no obstructions (plumbing, electrical conduit, air ducts, etc.)
and no unnecessary people present.
• Set up a well-marked safety zone with a roped boundary and clear signs.
• Provide adequate ventilation when working in an enclosed area. Breathing
exhaust gases is dangerous.
• To avoid electrocution, check for live electrical wiring near cutting area.

to spin without turning the chain which
can damage drive links.
When a chain stretches to a point where
the drive links are hanging approximately
1/2 in (12mm) to 3/4 in (18mm) below

if there seems to be usable segment left.
The chain typically determines life rather
than the segments wear.
STEP 7
Continue to lift up on the nose of the guide

CHAIN TENSION
Air Powered Chain Saw
IMPORTANT
A properly tensioned chain will optimize cutting performance. The tensioning rule of thumb for
a concrete cutting chain saw is that a properly tensioned diamond chain must not be bowstring
tight and can be pulled freely around the guide bar by hand easily without binding.
PROPER CHAIN TENSION
If the chain is too loose, it could come off the bar, or it will allow the drive
sprocket to spin without turning the chain, which can chew up the chain drive
links. If the chain is too tight, a lot of the saw’s power goes into turning the
chain rather than into the cut. In extreme over-tightened cases, the saw may not
be able to turn the chain at all. In addition, damage can occur to the bar nose
and premature stretch may occur.
HOW TO CHECK
Before cutting, check for proper tension by pulling the chain around the bar
by hand. If you cannot easily pull by hand, the chain is too tight and needs to
be loosened.
WHEN TO TENSION
All chains have a tendency to stretch when used. Diamond chains stretch
more than wood cutting chains because of the abrasive materials they are
cutting. When a chain stretches to a point where the drive links are hanging
approximately 1/2 in- 3/4 in (12 - 18 mm)below the bar, it’s time to tension
the chain.
HOW TO TENSION
To tension the chain, first loosen the side cover nuts, then while holding the nose of
the bar up, use a screw driver to turn the tensioning screw clockwise until the chain
drive links hanging below the bar are just beginning to enter the bar groove. Continue
to hold up on the nose of the bar and firmly tighten the side cover nuts, (20 ft-lbs,
27 Nm). And remember, it’s the side cover nuts that hold the bar in position.
HOW TO PREVENT CHAIN TENSIONER BREAKAGE
Do not attempt to adjust the tensioner without first loosening the side cover nuts. Do
not use the saw without making sure the side cover nuts are tight. If the side cover nuts
are not tight, the bar can slip backwards during cutting and break the tensioner pin.

AddITIONAl TENSIONING TIPS:
Concrete and ductile iron cutting chain saws operate with looser chain tension than wood chain saws.
It is common, especially on gas powered, concrete cutting chain saws to have the drive links hang
completely out of the bar. Wood cutting chain saws use oil to lubricate the chain. The oil makes the
chain very slippery and allows the drive links to fully nest between the teeth of the drive sprocket.
Concrete and ductile iron cutting chain saws require water for cooling and ushing the cut. Water is
not as good as oil as a lubricant. Also, there is debris mixed in with the water. As a result, sometimes
the drive links do not nest properly on the drive sprocket. When this happens, the chain acts like it
got tighter. There seems to be tight spots and loose spots as you pull the chain around the bar. If you
tension when the chain is in one of the loose spots, it will be too tight at some point in it’s rotation
around the bar. Rotating the chain completely around the bar by hand will let you know you have the
chain properly tensioned.
Additional Tips
1. To reduce chain stretch and tensioning downtime, a minimum water supply should be used:
- For ductile applications, a pump sprayer is sufcient.
- For concrete applications us 20 psi or greater water pressure.
2. Oil the chain at the end of the day to prevent rust but be careful not to over tension in this condition.
3. When pulling the chain around the bar by hand, be careful not to touch the bar with thumb or
forenger. The bar rails can be very sharp. Grab only the diamond segments to pull the chain.
The bar rails can be very sharp. Grab only the diamond segments to pull the chain.
4. Always turn the engine off before tensioning the chain.

PIPE CLAMP
Air Powered Chain Saw
Pipe Clamp Mounting Instructions
1. Assess pipe and area to cut. Ensure the chain saw will pass freely around any
objects in and around the path of the cut. (ie: power lines, telecommunication
lines, rocks, tools, etc.)
2. Ideally the pipe clamp should be mounted in a position that allows the locking
pliers to be on the top side of the pipe. This will allow for easier clamping.
3. US Saws recommends a bottom up cutting process. This allows two safety
functions.
a) With a bottom cut, a pipe will not sag in a fashion that will pinch the
bar. A top cut could cause pinching as a pipe sags.
b) The saw will be pulled through the cut by the operator and the bar will
swing away from the operators position. If the tool is pushed (downward
cut) the saw swings towards the operator.
4. Mount the receiver at a 10 o’clock position. This will allow the saw to hang in a
near vertical orientation.
5. Slide mounting pin on the saw (see pin installation instructions) into receiver
and install retainer clip.
6. Clear the area of loose debris that could get caught in the chain.
7. Use the saw according to operating instructions. Light pressure applied to the
handles is all that is required. Do not use levers, hang, or try to increase
leverage on the tool.
8. In some cases stopping your cut just before completion and leaving a tab
allows greater stability while making cuts down-line. Finish nal cut freehand
from the top to complete removal of section.

• Remove the rear bar stud nut.
• Install pin on rear bar stud.
• The inner thread of the pin will take the place of the nut.
• In certain applications (larger than 10” pipe) the mounting pin
may need to be relocated to the front bar stud for greater saw
clearance.
• Ensure the chain is adjusted according to the chain tensioning
guide.
Read and understand instructions provided with the saw and/
or pipe clamp before using this device. Use caution not to drop

IMPORTANT
OPER ATION
Never start a diamond chain saw without the bar, chain and side cover
properly assembled. Failure to do so may result in serious injury.
Always check hose connections before turning on air compressor.
Hold saw with both hands and ensure the chain is not contacting any
objects.
• Ensure Proper Chain Installation: Concrete chains should lead with the bumper segment into the cut.
Ductile chains can be mounted in either direction.
• Ensure Proper Chain Tension: The chain should be tight but easily pulled around the bar by hand.
• Ensure all safety devices are properly mounted and functional. Ensure all controls are in working
order.
• Be sure there are no obstructions (plumbing, electrical conduit, air ducts, etc.) and no unnecessary
people present.
• Always wear protective clothing, including hard hat, eye protection, hearing protection, non-slip safety
boots, and gloves. Avoid wearing loose tting clothing.
• Use Adequate Water Supply and Pressure:
Minimum Flow: 1gpm
Recommended Water Pressure: 20psi
• Use Proper Air Supply:

• Blow the air supply line clear before connecting to the saw.
• Check oil level; if necessary, re-ll oiler with ice-free air tool oil.
• The chain should travel away from the operator on the top side of the bar during operation.
Pre-Cut Checklist
The single most important factor an operator can control to increase chain
life is to use adequate water pressure. Insufcient water supply will result
in excessive wear to the chain which can lead to loss of strength and chain
breakage and/or damage to the guide bar nose sprocket.
• Select the proper chain type for the material being cut.
• Outline the cut with a permanent marker for a visual cutting edge.
• Avoid pinching the guide bar and chain. Always cut the bottom of an opening rst, then top, and then
the sides. Save the easiest cut for last.
• For the straightest cuts in concrete use the “Step Cut” method. First, score the entire cut line approxi-
mately a half-inch deep using the nose of the bar. Next, deepen the cut by about two inches. Then,
plunge all the way through and complete the cut.
• For the straightest cuts in pipe cutting applications cut from the bottom up using the Pipe Clamp.
• Be sure that cut material cannot fall and injure operator or bystanders.
• Check for live electrical wiring near the cut or in the concrete to avoid electrocution.
• Check for and remove all obstructions (plumbing, electrical conduit, air ducts, etc.) that may interfere
with the cut.

STOPPING THE SAW
• Toturntheengineoff,toggleignitionswitchtothe"STOP"position.Closewatervalve.
OPER ATION
Before cutting, make sure the pipe is in a safe condition to be cut. Sup-
port the piece you are going to be cutting in such a way that the cut will
remain open during the cut and when the cut is nished. Pinching the
chain during the cut could cause chain breakage and could result in
death or serious injury to the operator.
If using the pipe clamp accessory, the clamp must be attached in such
a way that it does not move during the cutting operation and/or when
the cut is nished. Unexpected movement of the clamp could cause the
operator to lose control of the saw resulting in death or serious injury.
With the saw engaged in any surface the operator should be aware that
the forces generated by the tool can force debris to be ejected from the
moving chain either away from the saw or towards the operator. Ensure
no bystander is located immediately in front of or behind the material
being cut.
Air Powered Chain Saw
Making The Cut
All concrete pipe cutting chain saws are considered specialty tools. The overall cutting
speed is slower that some other types of cutting equipment. For this reason the correct
time allocation should be made so that the operator has time to make the cut at a
safe pace and not have to force the saw to try and increase production. Forcing the
saw creates unneeded wear on chains, bars, and drive components. Additionally, long
periods of exertion can cause operator fatigue which can increase the likelihood of
injury.
When using the saw in a hand held fashion a slow rocking motion 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.
When cutting ensure that the water supply is sufcient for the cut being made.
1. Connect all ttings (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 difcult to
control.

TROUBLESHOOTING
• 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 requirements;
ideal performance can be achieved at higher volume.
• 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.
• 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.
• CHAIN TENSIONER BREAKAGE - Side cover nuts are not tight enough.
• WATER NOT FLOWING - Water hose is kinked, blockage in guide bar water ports, or
water supply is not turned on.
• MOTOR DOES NOT START -
• Insufcient air supply. Check compressor and air hose, valves, and air inlet
screen for blockage.
• Chain tension is too tight. Loosen chain tension.
• Iced exhaust. Wait until ice thaws, then lubricate with ice-free air tool oil.
• Vanes sticky. Apply lubricant directly to saw air inlet and blow motor clear. Re-
peat if necessary.
See Maintenance Instructions.

Air Powered Chain Saw

MAINTENANCE
Air Motor 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.
Service life and performance of the chain saw are determined by:
1. Degree of air purity
2. Lubrication
3. Maintenance
System Clean-Up
1. Run saw, with water on, for 15 seconds out of cut to ush 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 ttings on saw and compressor.
5. When nished cleaning saw, spray entire saw, chain, bar, and drive sprocket
with a light weight penetrating oil (ie: WD40). This will minimize rust and re-
duce build-up on saw assembly.
Lubrication
For every 50 hours of operation the motor will need to be greased. There is a
grease tting on the motor. It will need 2 pumps of standard bearing grease.
