5.  Fit the appropriate size bushing and 

sheave together and slide them onto the 
jackshaft. 

Note: Align the bushing with the jackshaft key 
in place on the shaft prior to installing, or drive 
the key into the key hole once the sheave and 
bushing are fully installed

. 

Note: Ensure the sheaves are properly aligned 
prior to securing them.  See “Aligning the Belt 
Sheaves” later in this section. 

6.  Place the two setscrews into the setscrew 

holes (in line with each other) on the 
bushing and retighten the setscrews to 
secure the bushing and sheave.

Saw), Blade Shaft Sheave, Transmission 
Sheave, and Engine Sheave 

1.  Remove the four setscrews (two on 

transmission sheave) from the sheave 
grooves. 

2.  Remove the sheave. 

Note: The transmission sheave must be 
removed prior to removing the engine sheave

3.  Align the appropriate size sheave with the 

drive key and fit the sheave onto the shaft. 

Note: If desired, drive the key into the key hole 
once the sheave is fully installed

.

Aligning the Belt Sheaves 

Always align the large jackshaft sheave with 
the engine sheave, and the small jackshaft 
sheave with the blade shaft sheave prior to 
securing the sheaves in place. 

1.  Use a straightedge (use skinny side of 

straightedge for least amount of bending) 
and place it against the outside edge of 
one of the sheaves. 

2.  Adjust either or both sheaves for alignment 

and secure in place.

Lifting 

CAUTION 

Always use a strap to lift the machine. 
Ensure the strap is rated high enough to 
handle the load. 

1.  Ensure the work area is clear of any 

obstructions and all personnel are at a safe 
distance prior to lifting the machine. 

2.  Using a properly rated strap, place the 

strap around the frame lift using a basket 
style hitch. 

3.  Slowly lift the machine only high enough to 

conduct the required work. 

Transporting 

Always secure the machine using tie down 
straps to avoid damage during transport.  

Never transport the saw with a blade attached. 

Note: Never tow the machine as this may 
cause damage to the drive components. 

Storing 

Complete the tasks listed below prior to storing 
the saw for longer time frames: 

•

  Turn off all switches and controls. 

•

  Remove blades. 

•

  Lower the saw completely to remove strain 

on the lifting mechanism. 

•

  Clean and wipe down the saw to remove 

dust, debris, and slurry from saw 
components. 

•

  Remove the battery and store in a proper 

location, out of reach from children.
