• Always disconnect the air supply and relieve pressure from supply lines
before performing maintenance on the saw.
• Diamond chains and guidebar require a minimum water pressure of 20 psi
(1.4 bar). Insucient water supply may result in excessive wear to the
guidebar or diamond chain, which can lead to loss of strength and diamond
chain breakage and damage the bar.
• When operating a compressor with greater than 90 psi (6 bar) it is
recommended to use a “service unit with pressure regulator” in line to
prevent over speeding the saw.
GENERAL SAFETY PRECAUTIONS
• Always wear protective clothing, including a hard hat, eye protection, hearing
protection and gloves.
• Avoid loose clothing.
• Perform safety checks before starting each day.
• Always operate tool with solid footing and handgrip.
• Remove or control slurry to prevent yourself or others from slipping while
cutting.
• Always work in a cleared area.
• Be sure there are no obstructions (plumbing, electrical conduit, air ducts).
• Set up a well-marked safety zone with a roped boundary and clear signs to
keep bystanders at least 20 ft (5m) away.
• Breathing exhaust fumes is dangerous. Provide ventilation in closed areas.
• To avoid electrocution, check for live electrical wiring near cutting area.

CORRECT CHAIN 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.
If the chain is too tight, more 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.
CHAIN TOO LOOSE
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 damage drive links.
When a chain stretches to a point
where the drive links are hanging
approximately 1/2 in (12 mm) to 3/4
in (18 mm) below the bar, it is time to
tension the chain.

OPERATION
1. To reduce chain stretch and tensioning downtime, use 20 psi (1.5 bar) 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 sure to wear gloves. The
bar rails can be very sharp. Grab only the diamond segments to pull the
chain.
4. Always pull the chain away from the WallWalker®. The point of the
WallWalker can also be very sharp.
Concrete cutting chainsaws operate with looser chain tension than wood
chainsaws. It is common, especially on gas powered, concrete cutting
chainsaws to have the drive links hang completely out of the bar. Concrete
cutting chainsaws require water for cooling and flushing the cut. Rotating the
chain completely around the bar freely by hand will let you know you have the
chain properly tensioned.
Before tensioning chain, always turn the compressor off and relieve system
pressure before disconnecting from the compressor.
If tension is too tight, it will lead to excessive chain stretch, and a lot of the
saw’s power will be used to overcome friction. In severe cases the chain may
not turn at all and can lead to chain breakage. If the tension is set too loose,
the chain could be thrown off of the bar, or allow the sprocket to turn with out
turning the chain, which will damage the drive links.

• Adequate Water Supply and Pressure:
Minimum Flow: 1 gpm (4 lpm)
Minimum Water Pressure: 20 psi (1.4 bar)
Checking for water pressure without a pressure gauge: With the compressor
o, attach water hose to the saw water connection. Pull the chain o to one
side of the bar and turn on the water valve. If there is a minimum of 20 psi,
water should spray 1 - 3 ft (.5 to 1 m) from the bar.
• Proper Air Supply to the Saw:
Maximum PSI: 90 (6 bar)
Maximum CFM: 124 cfm (3.5 M3/min)
Insure the air supply line is clear before connecting it to the saw. Dirt and
water separators are recommended to prevent rust and condensation from
forming in the air lines.
• Motor Lubricator: (Not Included)
Always use an in-line oiler to provide continuous lubrication to the air motor.
This will increase the life of the saw and reduce down time.
Check oil level, when necessary; ll with resin and acid-free SAE 5 W to
SAE 10 W oil.
In winter or when using very moist air, use antifreeze lubricant, such as “ICS
Prolube ATL/AF”, “Killfrost” “BP Energol AX10” or “Kompranol”

• Select the proper chain for the material being cut.
• Outline the cut with a permanent marker for a visual cutting guide.
• Avoid pinching the bar and chain. Always cut the bottom of an opening rst,
then top, and then the sides. Save the easiest cut for last.
OPERATION
If cutting pipe with PowerGrit® be sure the cut line stays open by providing
proper pipe support. Also check for neighboring utilities or obstructions.
Concrete is very heavy, 1 cubic foot (30 cubic cm) weighs 150 lbs (68 kg). Be
sure to cut so that concrete cannot fall and injure operator or bystanders.
Check for live electrical wiring near the cutting area or in the concrete to
avoid electrocution which can result in death or serious personal injury.

OPERATION
• When cutting reinforced concrete, be sure you are always cutting
concrete as well as rebar. This will prevent the segments from glazing
over and keep the diamonds exposed. Also, expect less chain life when
cutting concrete with heavy rebar.
• When replacing a chain, ip the guidebar over and dress your
guidebar rails to maintain straight cuts. Guidebar rails can be dressed
with a at le or belt sander.
• Note: The normal life of a guidebar is 2 to 3 chains. However, heavy
rebar can shorten guidebar life too.
• When using a new chain, cutting speed can be increased by
“opening up the diamonds”. Make a few plunge cuts in an abrasive
material such as a cinder block.
Over time, these components
can develop sharp edges and cause cuts.

701A SERIES OPERATOR’S MANUAL

OPERATION
• When cutting into concrete, plunge cut instead of starting at the top
of the wall. This will reduce chatter, extend diamond life, create a
straighter cut and more quickly enable the use of the Wallwalker®.
• Always operate a diamond saw at full throttle. If too much force is
applied, the saw will lug or stall and the chain will not have enough
speed to cut eectively. If too little force is applied, the diamonds will
skid and glaze over.
• For the straightest cuts use the “step cut” method. First score the
entire cut line with the nose of the bar approximately ½ inch (12 mm)
to 1 inch (25 mm) deep. Next, deepen the cut by about 2 inches (50
mm). This groove will help guide the bar for a straight cut.
Then plunge all the way through and complete the cut using the
Wallwalker®.
• Use the Wallwalker to cut eciently and reduce operator fatigue. The
Wallwalker when extended is a fulcrum that converts inward force to
downward force and will develop a 4-to-1 mechanical advantage. To
use correctly, plunge into the wall and simply engage the point of the
Wallwalker into the cut and push straight in. The Wallwalker will force
the saw to feed down.

1. Run saw, with water on, for 15 seconds out of cut to ush slurry and debris
from chain, bar and drive sprocket.
2. Wash concrete slurry from saw body.
3. Remove bar and chain. Flush out chain tensioner assembly location with
high water pressure and lube with grease.
4. Clean all air ttings on saw and compressor.
5. When done cleaning saw, spray entire saw body, chain, bar, and drive
sprocket with a lightweight penetrating oil. This will minimize rust and
reduce slurry build up on saw assembly.

- Be sure the compressor is providing the correct
air pressure at the saw (90 psi = 6 bar) and cubic feet per minute
(124 cfm = 3.5 m3/min)
- Diamonds may be “glazed over”. Make
a few plunge cuts in an abrasive material such as a cinder block to expose
the diamonds.
NOTE: This does not apply to PowerGrit® chains.
- Not enough water pressure, the
minimum water pressure is 20 psi (1.4 bar). Insucient water supply will
result in excessive wear on the chain, which can lead to loss of strength
and chain breakage. Cutting with the guidebar nose buried in the cut, in
sand, gravel, pipe or using with improper chain tension will all contribute to
increased chain stretch.
NOTE: This applies to PowerGrit chains also.
- Side cover nuts are not tight enough, or
tensioning was attempted with side cover nuts already fully tightened.
- Water hose is kinked, blockage in guidebar
water ports, or supply is not turned on.
• Insucient 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 use anti-freeze lubricant
• Vanes sticky. Apply lubricant directly to saw air inlet and blow motor
clear. Repeat if necessary. See maintenance instructions
