come to a complete stop, install the cutter wheel lock pin, place the cutter wheel on the ground, disconnect
battery, and make sure the ignition key is in your possession.
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.
NOTICE
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 the case drain
pressures and damage the shaft seals.
