OPERATING INSTRUCTIONS
Experience is very important when running the
5000
saw. A
skilled worker is highly recommended. Always do an inspection
of the saw before starting the engine. Check the fuel (W) and
oil level (Y) 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 work-
ing order. Check for loose bolts or nuts. Check for fuel or oil
leaks. Insure all guards are secure, undamaged and properly
installed.
To start the engine, turn the key switch (C) to the “ON” or “1”
position to activate the rocker switches. Raise the saw by
pushing the blade rocker switch (N) on the instrument panel to
the full up position. Pull the saw forward speed lever (G) rear-
ward until it stops. Make sure the red emergency stop button
(D) is in the “up” position.
The saw will not start unless the
emergency stop is “up”
.
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!
Check the air filter and clean or replace if necessary. Check
for proper specification of blade and that the skid plate oper
-
ates 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 confined or badly ventilated
area can result in injury or death due to asphyxiation
or carbon monoxide poisoning.
Open the engine throttle lever to full open position for maxi-
mum engine speed by pushing the engine speed rocker switch
(I). Lower the front guide to the full down position by depress-
ing the guide arm rocker switch (H).
Line up the saw with the cut line using the front guide wheel,
the rear guide (Q), and the triangle pointer on the back of the
blade block. Press the blade rocker switch (N) to lower the
blade in the concrete slowly to the desired depth (S) shown on
the back of of the blade block.
Move the saw forward by slowly pushing the forward speed
lever (G) until the desired cutting speed is reached. 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.
Move the saw at about half speed for the first 200 feet to al
-
low the blade to develop good diamond exposure or open up
and promote full blade life. Increase the forward speed of the
saw until the blade and the engine are working at maximum
efficiency.
Close the engine choke (A) by pulling up on the knob. 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” or “2” position and release once the engine starts.
Slowly open the choke (A) by pushing down on the knob. Allow
the engine to warm for a few minutes.
NOTE:
The hour meter (F) runs when the key is “ON” even if the
motor is not running.
