moving parts to stop before accessing the drive
wheel release valves.
WARNING

very hot. Touching a hot engine or hydraulic drive
units can cause severe burns.

hydraulic drive unit, under the seat.
Note: Make sure the release valves are in the fully horizontal
position when operating the machine or severe damage to the
hydraulic system can occur.
