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 operate saw if there is a fuel leak!
Insure all guards are secure, undamaged and properly in- stalled.
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 (D) and clean or replace if necessary. Check for proper specification 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.
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
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 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.
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.
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.
Move the saw at about half speed for the first 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 efficiency.
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.
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.
WARNING
Do not leave the saw unattended while the engine is running! Always secure the saw from movement while unattended.
Always clean the blade block assembly thoroughly before stor- ing the saw. Always close fuel valve before transporting.
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 find damage or are suspicious that something appears to be dam- aged.
