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.

.Adjust safe maximum drive speed by unlocking

and adjusting the stationary bar to limit amount

of forward movement of the control levers.
Secure the stationary bar firmly by tightening the ~ lever on the left

side of bar.
