Hydrostatic Drive 

Disengagement Adjustment 

 

When the engine is not running, the grinder cannot be moved, 
since the hydrostatic drive is in locked position On the 
beltguard side, there is a handle push handle forward and 
down, this will unlock the hydrostat unit and allow 
freewheeling.  

 

When the engine is running, there is power to the 
transmission, Be careful to only move slowly, the control valve 
to transport the machine in a forward or reverse direction. The 
travel speed is determined by the rpm  of the engine, and how 
quickly the control valve is moved. 

 

When using grinder on unlevel ground, the grinder may have a 
tendency to creep down hills. The brake control located on the 
control panel can be pulled so as to lock the disc brake on the 
transmission. 

 

Caution:

 Damage can occur to Brake if to much pressure is 

applied.
