Great Dane GDSZ48-16BV, GDSZ61-22KHE, GDSZ52-22KHE manual Assembly of Machine, Initial Adjustments

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.

.Test function of the three safety interlock Systems.

.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.
