Hayter Mowers Condor hydrostatic Drive 510D - Manual (Page 32)

1.32 1.32 MAINTENANCE
Daily and Before Use continued
Check hydrostatic unit oil level: Always check,
prior to starting, when the mower is cold. Remove
the reservoir cap and check the fluid level. The
level should not be above the ‘cold’ mark. Top up,
if necessary to the cold mark with the
recommended grade of transmission fluid, refer
to SPECIFICATIONS, and replace the reservoir
cap. If the natural colour of the transmission fluid
has become ‘milky’ or black, it is possible that an
overheating or water contamination problem exists.
In such cases, the mower should be checked by a
Hayter dealer and the oil should be changed, refer
to MAINTENANCE - EVERY 200 HOURS.
IMPORTANT: PREVENT DAMAGE - Do not
overfill as this will reduce the expansion vol-
ume in the reservoir and leakage may occur
at operating temperature. If frequent topping
up is required, locate and repair any leaks.
Operation at a low fluid level may result in
permanent internal damage.
Check the operator presence controls: Stop the
engine.
Check the operation of the microswitches, ensure
the operation arm is free of any debris and that
the roller rotates freely. Spray the hydrostatic unit
neutral detent microswitch with a water repellent
lubricant.
Engage the cutterhead drive and operate the OPC
levers. The engine should not start when the
normal starting procedures are followed.
Start the engine, engage the cutterhead drive and
operate the OPC levers. Release the OPC levers
and ensure that the cutterblades cease to rotate
within 5 seconds.
Operate and hold the travel rocker lever in the
forward travel direction. The engine should not
start when normal starting procedures are fol-
lowed. Carry out a similar check for reverse travel.
WARNING: PREVENT ACCIDENTS - Keep
bystanders away when checking the opera-
tor presence control system. DO NOT use the
mower unless the operator presence controls
work correctly as described below. Consult your
Hayter dealer if the system malfunctions.
