OPERATING INSTRUCTIONS
Experience is very important when running the 4000 saw. A
skilled worker is highly recommended. Always do an inspection
of the saw before starting the engine. Check the fuel (J) and
oil level (G) per the enclosed engine manual. SAE 10W/30 oil
and unleaded gasoline with an 87 or higher octane should be
used. The hydrostatic tansmission use Mobil DTE 26 hydraulic
oil or equivalent (20W with viscosity of 68). Observe all safety
regulations for the safe handling of fuel. Always check the
engine oil with the saw turned off, completely lowered and
the engine level! Check that all controls are in good working
order. Check for loose bolts or nuts. Check for fuel or oil leaks.
WARNING
Do not leave the saw unattended while the engine
is running! Always secure the saw from movement
while unattended.
Insure all guards are secure, undamaged and properly in-
stalled.
To start the engine, turn the key switch on the “ON” (C) po-
sition. Raise the saw by pushing the rocker switch (P) on
the right handle to the full and up position. Move the engine
throttle lever (O) 1/3 of the way to the open position. Close the
engine choke lever (F). The closed choke position enriches the
fuel mixture for starting a cold engine. The open choke position
provides the correct fuel mixture for operation after the engine
starts and for restarting a warm engine. Start the engine by
turning the key switch (C) to “START” position and release
once the engine starts. Slowly close the choke lever (F). Allow
the engine to warm for a few minutes.
WARNING
Do not operate saw if there is a fuel leak!
WARNING
Do not operate the saw unless all guards, safety
equipment and the engine kill switch are in place and
operational!
Always clean the blade block assembly thoroughly before stor-
ing the saw. Always close fuel valve before transporting.

Check the air lter (D) and clean or replace if necessary.
Check for proper specication of blade and that the skid plate
operates properly. Check that the blade and skid plate are in
good condition. Make sure the work site is clean, well lit and
hazard free.
WARNING
ASPHYXIATION HAZARD
Running an engine in a conned or badly ventilated
area can result in injury or death due to asphyxiation
or carbon monoxide poisoning.
WARNING
Before each use, carefully inspect the 4000 for any
damage to any of its parts and components. Pay
careful attention to any leakage of gasoline or oil.
Under no circumstance should the 4000 or any of
its attachments be operated if you nd damage or
are suspicious that something appears to be dam-
aged.
Open the engine throttle lever to full open position for maxi-
mum engine speed by pulling the throttle knob (O) at the han-
dle. Lower the front guide to the full down position by pushing
the control handle (N) on the right forward.
Pulling the handle back slows the forward speed. Pulling the
handle to the full back position stops the saw. Keep the front
guide wheel on the cut line to insure straight cuts. Make small
adjustments by applying side pressure on the handle to keep
the saw straight.
Increase the forward speed if the saw is pulling left. Decrease
the forward speed if the saw is pulling right. Do not force the
saw. When approaching a wall, raise the front guide and use
the triangle guide at the back of the blade block to cut the last
few feet.
Line up the saw with the cut line using the front guide wheel
and the triangle pointer on the back of the blade block. Pull
the control lever (M) on the left back towards you to a full stop
position.
Lower the saw in to the cut by pressing the rocker switch (P)
on the right handle to the “DOWN” position. Lower the blade to
full depth. Move the saw forward by slowly pushing the control
lever (M) on the left forward until the desired cutting speed is
reached.
Move the saw at about half speed for the rst 200 feet to allow
the blade to develop good diamond exposure or open up and
promote blade life. Increase the forward speed of the saw until
the blade and the engine are working at maximum efciency.
Do not hit the blade block assembly against any object. Dam-
age may result. Slow the forward speed by pulling the control
handle lever back until the saw stops. Raise the saw out of the
cut to maximum height by depressing the rocker switch in the
“UP” position.
The self propel function of the saw will not operate with the unit
raised. Move the engine throttle lever to the full closed posi-
tion. Turn the engine kill switch to the “OFF” position.
