FILTER REPLACEMENT
The Brake /Steer Valve is located on the turntable, under
the hydraulic tank. The hydraulic oil filter cartridge is in
this valve and is recommended to be replaced every 6
months or sooner if the hydraulic controls become slow.
To replace, remove the 1-3/8 hex plug w/o-ring. The filter
can now be pulled out. Only the oil in the filter will be
present. Insert the filter cartridge into valve to bottom.
Adjust the slotted head screw to be level with outside sur-
face of the valve, and replace the hex plug.
