633GC / 633F4 OPERATOR’S MANUAL

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.

STOPPING THE SAW
• To turn the engine off, toggle ignition switch to the "STOP" position. Close water valve.
OPERATION
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 finished. 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 finished. 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 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.
