HYDRAULIC SECTION
NOTE:
When returning hydraulic components for warranty make sure to box up all warranted parts to avoid
additional damage while shipping.
Do not disassemble any hydraulic components which are to be warranted.
Anything which has been disassembled or tampered with will not be warranted. Items being returned must be
clean. All hydraulic components must have all hosing ports plugged. Failure to plug ports will allow debris to
enter components which will void warranty.
NOTE:
In cold weather situations let the hydraulic system idle for approximately 15 minutes to allow the system
to warm up to operating temperature. Running cold oil through the hydrostatic motor can raise case drain
pressures and damage shaft seals.
