HYDRAULIC SYSTEM

Hydraulic Fluid Reservoir

The hydraulic fl uid reservoir is located behind the right side 
door under the operator seat.  (See Fig. 1)

Note:

 The reservoir fi ll cap has a built-in breather and dip 

stick.  Replace the cap every 100 hours of operation.

Note:

 The hydraulic oil fi lter contains a replaceable element.  

Replace the fi lter element every 100 hours of operation.

The reservoir has a sight gauge to quickly view if there is a 
suffi  cient amount hydraulic oil in the reservoir tank to run the 
machine.  Check daily and add hydraulic oil as needed. 

When the machine is cool unscrew the fi ll cap and check the 
fl uid level on the attached dip stick.  The fl uid level should 
be between the high and low markers.  The cap should be 
screwed down hand tight and unscrewed to get a proper oil 
level reading.  Add or remove hydraulic fl uid as needed.  

 CAUTION

DO NOT OVERFILL HYDRAULIC RESERVOIR TANK!                                                                                      
DO NOT USE TRANSMISSION FLUID!
