.Test function of the three safety interlock Systems.
HYDRAULIC SAFETY
.All hydraulic system servicing should be done by a qualified
technician.
.Relieve all pressure in the system before disconnecting any
hoses.
.Keep body and hands away from pin holes that may eject
hydraulic fluid under high pressure.
.Make sure all hydraulic connections are tight and hoses in
good condition.
High pressure hydraulic fluid may have sufficient force to
penetrate skin and cause serious injury. Seek medical attention
immediately. Treatment must be done a doctor.
ASSEMBLY OF MACHINE
Please note the Great Dane Surfer is shipped completely
assembled and has been tested at the factory.
After you have removed all crating and packaging materials,
carefully follow these steps:
.Remove battery from machine, if one is installed and service
observing precautions in Section on Battery Servicing.
.Check hydraulic fluid level. Should be about 5 inches below
the top of the oil filler pipe. Use 10W-30 engine oil during
initial operating period.
.Check engine oil for proper level.
.Check rear wheel tire pressure. Use high pressures up to 24
psi for mowing on rough ground, and down to 14 psi for fairly
smooth terrain. Note, front caster wheel tires must be foam
filled and thus never require air servicing.
.Remove belt cover and check all belt tension. .Lubricate all
moving parts (see Maintenance
Check List).
.Locate rear drive wheel mounting bracket for general height of
cut in your region.
.Fill fuel tank with regular, 80 octane gasoline. .Open shut-off
valve under gas tank.
You are now ready for initial running of the machine.
INITIAL ADJUSTMENTS
.Set the rear of the machine on jack stands or blocks to raise
rear wheels off of ground and block caster wheels.
.Start engine. Let run for several minutes to warm hydraulic
fluid.
.Observe that wheels rotate in the correct direction when
control levers are moved back and forth.
.If wheels do not stop rotating when controls are.~ in neutral, adjust
the NEUTRAL stop wing bolts at the rear of the power unit,
between the two hydro pumps.
.Engage cutter blade clutch. Be sure area is clear
of debris. Run blades for several minutes.
.Shut off engine and remove jack stands.
Remove start key.
.Check all belts for proper tension.
.Test run the machine in a level area. If machine
drifts to the right or left when both control levers
are full forward, adjust swivel nuts at the top of
control rods to change length of control rod so
that machine travels in a straight line. Please remember, the
neutral adjustment and straight
drive adjustments will need to be repeated after several hours of
operation.
