Husqvarna soff-cut 150 用户手册

Experience is very important when running the 

150 saw. A 

skilled worker is highly recommended. Always do an inspec-
tion of the saw before starting the engine. Check the fuel (H) 
and oil level (A) per the enclosed engine manual. SAE 10W/30 
oil and unleaded gasoline with an 87 or higher octane should 
be used. 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! Do not screw the oil 

dipstick into the oil filler neck to check the oil 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 fuel valve (C) on by the carburetor 
on the side of the engine. Raise the blade by pushing down on 
the handle bar with both hands to the full and locked position. 
Turn the engine kill switch (J) to the “ON” or “1” position. Move 
the engine throttle lever (E) 1/3 of the way to the open position. 
Close the engine choke lever (D). 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 pulling the rope handle (F) on the side of the en-
gine. After the engine starts, slowly open the choke. Allow the 
engine to warm for a few minutes.

Open the engine throttle lever to full open position for maxi-
mum engine speed. Line up the saw with the cut line using the  
white wheel on the front guide and the triangle pointer on the 
back of the blade block. Push down on the saw handle and 
pull the blade release lever to lower the blade in the concrete 
slowly. Push the saw forward to cut keeping the front guide 
wheel in the cut line. Push the saw at about half speed for 

the first 50 feet to allow 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 engine are 

working at maximum efficiency. 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. Push down on the back of the handle bar to 
raise the saw out of the cut to the full locked position. Move the 
engine throttle lever to the full closed position. Turn the engine 
kill switch to “OFF” or “0” position.

Always clean the blade block assembly thoroughly before stor-
ing the saw. Always close fuel valve before transporting. The 
saw will leave two trails of concrete cuttings. Lightly sweep the 
cutting parallel to the cut with a soft bristle broom. Do not walk 
on the joints or transport equipment across the joints until 
the concrete fully hardens.

Check the air filter (G) 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. Check that the handle is in full upright position 
and pinned. Check that the front guide is rotated to the forward 
position. Make sure the work site is clean, well lit and hazard 
free.
