Husqvarna 4000 用户手册

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). 

regulations for the safe handling of fuel. Always check the 

the engine level! Check that all controls are in good working 

order. Check for loose bolts or nuts. Check for fuel or oil leaks.

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.

Always clean the blade block assembly thoroughly before stor-

ing the saw. Always close fuel valve before transporting.

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.

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. 

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 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.

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.
