OPERATION INSTRUCTIONS / /MAINTENANCE (continued)
IMPORTANT:
Keep the tires properly inflated (approx. 80 psi). Both under and over inflation can greatly reduce tire life.
Inspect bracing and welds and repair if needed. Failure to repair could cause extensive damage and
greatly reduce the life of the unit.
Inspect tie rods and replace the bronze bushings in the steering assembly when needed.
Repack the bearings in the hub assemblies once a year or as needed. Use a good quality bearing
lubricant such as Bearing Gard MK1 or equivalent. NOTE: Grease zerks on hubs caps are for between
scheduled service lubrication.
If equipped with brakes, inspect the drums periodically for wear and for brake line damage. Check fluid in
the master cylinder and inspect for dirt or corrosion on the inside wall of the master cylinder. Clean and
replace with new Silicone Brake Fluid (DOT 5) if needed. Wagons with brakes should be stores in a
clean, dry place when not in use.
ADJUSTING THE DRUM BRAKES
It is necessary to rotate the wheels in the direction of forward rotation only when making adjustments.
The brake adjustment nut is located behind a slot at the bottom of the backing plate. Tighten the nut until
you cannot rotate the wheel by hand, then back off the adjustment 18 to 20 notches.
