COLD ENGINE STARTING PROCEDURE
1. Toggle the ignition switch to the "START" position and pull the
choke lever out.
2. Lock the throttle in the start position by depressing the trigger (A)
and trigger interlock (B) at the same time.
3. Depress and hold throttle lock button (C) while releasing the trigger
and trigger interlock in succession.
4. Open the water valve 1/4 turn.
5. Place the diamond chainsaw on the ground making sure the chain
is free of any obstructions.
6. Place right foot on the base of the rear handle.
7. Place left hand on front handle.
8. With right hand, slowly pull starter handle until the starter pawls engage.
9. Pull the starter cord (
hard, fast, short pulls
) until engine fires or "pops" - should be 1 to 7 pulls.
10. Push the choke lever in.
11. Pull the starter cord until engine starts - should be 1 to 2 pulls.
12. When the engine starts, allow the engine to idle. Pull on the throttle trigger several times to help
warm up the engine.
13. Open the water valve completely.
CAUTION
STARTING AND STOPPING A DIAMOND CHAINSAW
Never start a diamond saw without the bar, chain and side cover
properly assembled. Otherwise, the clutch can come loose and
cause personal injuries.
Always move a diamond chainsaw at least 10 feet (3 m) away from
the fueling area before starting.
Place the diamond saw on clear ground. Ensure that secure
footing is established and chain is not contacting any objects.
IMPORTANT
WARNING
WARM ENGINE STARTING PROCEDURE
1. Use the same procedure as starting cold engine, but
DO NOT pull choke lever out
. If choke is used, the
carburetor will flood with gas.
2. If the engine does not start in 3 hard, fast pulls with the throttle locked, unlock the throttle and pull the
starter cord 3 more times.
Note: To hold the trigger fully open it may be necessary to insert right foot into rear handle opening
and twist.

PRE-CUT CHECKLIST
• Proper Chain Installation: The bumper should lead the segment into the cut, double bumper
chains may be mounted in either direction.
• Proper Chain Tension: The chain should be tight but easily pulled around the guide bar by hand.
• Ensure all safety devices are properly mounted and functional and that all controls are in proper
working order.
• Be sure there are no obstructions (plumbing, electrical conduit, air ducts) 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 fitting clothing.
• Adequate Water Supply and Pressure:
Minimum Flow: 2 gpm (8 lpm)
Minimum Water Pressure: 20 psi (1.5 bar)
• Diamond chains with SealPro
®
require a minimum
water pressure of 20 psi (1.5 bar).
PLANNING THE CUT
• Select the proper chain type for the material being cut.
• Outline the cut with a permanent marker for a visual cutting guide.
• Avoid pinching the guide bar and chain. Always cut the bottom of an opening first, then top, and
then the sides. Save the easiest cut for last.
• For the straightest cuts use the “Step Cut” method. First score the entire cut line approximately 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 using the Wallwalker
®
.
• Be sure cut concrete cannot fall and injure operator or bystanders. Concrete is very heavy,
one cubic foot = 12”x12”x12” = 150 lbs. (30cm x 30cm x 30cm = 68kg).
• Check for live electrical wiring near the cutting area or in the concrete to avoid electrocution.
The single most important factor an operator can control to
increase chain life is to use adequate water pressure. Insufficient
water supply will result in excessive wear to the chain, which can
lead to loss of strength and chain breakage.
IMPORTANT
OPERATION
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 fitting clothing.
• Use Adequate Water Supply and Pressure:
Minimum Flow: 1gpm
Recommended Water Pressure: 20psi
• Use Proper Air Supply:
Minimum PSI : 90
Minimum CFM: 90
• Blow the air supply line clear before connecting to the saw.
•
Check oil level; if necessary, re-fill 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. Insufficient 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 first, 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.
