Hydraulic System Maintenance
Hydro-Gear recommends that the fluid and filter(s) be changed every 500 hours. Use any
type of motor oil in a 5W-40 Synthetic or equivalent.
Hydraulic system requires 25 micron hydraulic filters (part # 80404) or equivalent to be
used.
Check for hydraulic leaks daily to ensure proper fluid levels.
**Remove line(s) coming from the filters (at hydro pump end) to drain fluids**
After draining fluids, re-install hydraulic lines and tighten. Remove Hydraulic Filter and
replace with part # 80404 or equivalent. Tighten down and mark the hours the unit
currently has on the filter (with permanent marker). Remove Hydraulic Tank cap and fill
to mark (approximately 2/3
rd
to the top of tank) and re-install Tank Cap. Using a Floor
Jack or equivalent, lift the rear tires off the ground so that you can run the tires in the
forward and reverse positions without the unit moving (chock both the front and the back
of the front traction unit tires and if desired, block the frame for safety). Turn the unit on
and slowly run the rear wheels forward and then backward (repeating this process a few
times). This will purge any unwanted and unneeded air out of the system.
Turn off the unit, apply the parking brake and bring the unit back down to the surface.
Remove any chocks securing the front wheels and Floor Jack or equivalent out from
under the backside of the unit. Turn unit on, release parking brake and move the unit
forward and backward a few times. Hydraulic oil change completed.

Traction Unit Maintenance
The Z-Spray has 4 grease fittings that require periodic greasing. These locations can be
found on the wheel assembly (1 on each front wheel assembly) and on the caster
assembly (1 on each front caster assembly).
