SAFETY RULES

A TTENTION! BECOME ALERT! YOUR SAFETY IS INVOL VED!

Safety is a primary concern in the design and manufacture of our products. Unfortunately , our efforts to provide
safe equipment can be erased by an operator’s single careless act. In addition, hazard control and accident
prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in
the operation, transport, maintenance and storage of equipment.

Make certain that the operator(s), prior to operating is instructed in safe and proper use and reviews and
understands the manual(s) pertaining to this machine.

Read this manual before you operate this machine. If you do not understand any part of this manual, or need
more information, contact the manufacturer or your authorized dealer .

SAFETY

Understand that your safety and the safety of other persons is measured by how you service, and operate this
machine. Know the positions and functions of all controls before you try to operate them. Make sure to check
all controls in a safe area before starting your work.

The safety information given in this manual does not replace safety codes, federal, state or local laws. Make
certain your machine has the proper equipment as designated by local laws and regulations.

A frequent cause of personal injury or death is from persons falling of f equipment and being run over. Do not
permit persons to ride on this machine.

Travel speeds should be such that complete control and machine stability is maintained at all times. Where
possible, avoid operating near ditches, embankments and holes. Reduce speed when turning, crossing slopes
and rough, slick or muddy surfaces.

Collision of high speed road traffic and slow moving machines can cause personal injury or death. On roads,
use flasher lights according to local laws. Keep slow-moving-vehicle emblem visible. Pull over to let faster
traffic pass.

Never adjust, service, clean, or lubricate running gear until all power is shut off.
Keep all safety shields in place.
Keep hands, feet, hair and clothing away from moving parts while unit is in operation.
Make sure that everyone is clear of equipment before applying power or moving the machine.
Make sure that the running gear is fastened securely to the tractor by using the proper hitch pin, clip and safety

chains.
Never overload the running gear. Overloading the running gear is dangerous and can cause extensive damage.

Do NOT exceed load limit or speeds in excess of 20 MPH. Rims, hubs and bearings are designed for heavy
loads at slow speeds. Also be sure slow moving vehicle emblem is attached to rear of wagon.

Before unhooking the running gear from the towing unit, be sure to properly block the wheels to prevent the cart

Brake Systems Only.

IMPORTANT: Set-up work to be performed by qualified servicemen only.

Mount tires on the wheels and inflate per the tire manufacturer’s recommendations and instructions.

1)
Mount the wheels to the hubs and tighten the flat hub nuts to 260 ft. lb torque. Check the hub nuts

2)
after the first hour of operation, then every 10 hours of operation for the first 40 hours of use. These

nuts must be kept tight at all times. Wheels that are improperly installed on the running gear,
resulting in product failure, will nullify the warranty and shift the burden of liability to the owner/
operator of the equipment.

Slide the coupling pole into the front and back assemblies, slipping the collar in the back assembly .

3)
When mounting to a 540SD gravity box, spacing of the coupling pole (approximate distance between
holes on the coupling pole) should be 44”. Distance from center of axle to center of axle is
approximately 124”.

4)

Attach either the rocking bolster or the standards (box attachment brackets) to the running gear .
Fasten the tongue to the front assembly using the tongue bolt (remove paint from the bolt before

5)
attaching) and jam nut. Attach the tongue spring to the bracket on the tongue and hitch assembly.
For running gears without brakes, check underneath the tongue and make sure that the safety catch
(7/8” x 2 1/4” bolt w/spacer) is secure.

Mounting Brake Lines to Running Gear with Hydraulic Disc Brakes. IMPORTANT : Running Gears

6)
with Hydraulic Disc Brakes should be set up immediately after delivery from factory to prevent dirt
and moisture from entering brake system. Att ach the brake lines and hoses per drawing for Optional
Hydraulic Disc Brake System. Be careful not to over tighten the fittings and strip the threads.
Always use DOT 5 Silicone Brake Fluid or equivalent. On Optional Hydraulic Disc Brakes Systems,

be sure to remove paint from disc brake rotors before bleeding brake lines. Failure to
remove paint will cause brakes to not work properly . If running gear is stored for an extended
period of time, the brake discs will need to be cleaned with steel wool (be sure the brake
pads are not rusted fast to the brake disc). Also, check Caliper Retainer Area for free
movement. Free retainer and caliper from any seized paint or dirt by tapping retainer and
spring with a rubber or wood mallet.

SET-UP INSTRUCTIONS FOR RUNNING GEAR (Continued)

IMPORTANT: Set-up work to be performed by qualified servicemen only.

7)

Adding Brake Fluid to Master Cylinder (for optional brake system).
IMPORTANT: Do NOT shake the brake fluid container . A VOID agitating the system when bleeding.

Do NOT “pump” the brake plunger . Instead, depress and release slowly .
Fill the master cylinder carefully, pouring the fluid down the side of the reservoir to minimize air

entrainment.
METHOD ONE (requires two people)
Close all bleed screws.
St art with the wheel furthest from the master cylinder. Slip a transp arent bleed hose on the bleeder

stem and place the other end of the hose in a clean container which is partially filled with fluid at all
times.

The first person depresses the brake plunger SLOWLY (take 3-5 seconds). THEN the second
person opens the bleed screw. He then closes the bleed screw BEFORE the first person SLOWLY
releases the plunger (3-5 seconds). Continue until there is no evidence of air in the bleed hose.
Continue with remaining wheel working from the longest to the shortest distance from the master
cylinder. T op of f master cylinder as needed to prevent reintroducing air into the lines.

REMEMBER:

1) Depress plunder slowly

2) Open bleed screw

3) Close bleed screw

4) Release plunger slowly
METHOD TWO (one person)
Attach bleed hose to rear wheel as in method one. Open bleed screw . SLOWLY depress plunger (3-

5 seconds) Let plunger return SLOWLY (3-5 seconds). Repeat until line is air free. Close bleed
screw. Top off master cylinder as needed to prevent reintroducing air into lines.

Repeat with remaining wheel.
Contamination with dirt, water , petroleum products or other materials may result in brake failure or

costly repairs.

8)

MOUNTING WHEELS
Figure One shows the proper way to mount wheels with straight holes.

(22.5 x 13.5 wheels)
Use flange wheel nut (valve stem is on the outward side of the tire).
Wheels that are improperly installed on running gears, resulting in product

failure, will nullify warranty and shift the burden of liability to the owner/
operator of the equipment.

IMPORTANT: Make sure to properly attach the gravity box (or other equipment) to the running gear.
Bolt all four corners of the gravity box runners to the running gear. (If the box is used in rough terrain
and it is not equipped with a rocking bolster, bolt a minimum of two corners and chain (or cable) the
remaining corners to allow more box flexibility).

OPERATING INSTRUCTION / MAINTENANCE

BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING EQUIPMENT.

Before equipment is put into service:
Has this manual and the operator’s manual on the gravity box been read and clearly understood by the

operator(s) of this machine?
Have all braces, bolts, nuts, lug bolts, and lug nuts been checked to ensure that they are properly fastened?
Is the running gear properly fastened to the tractor? Use a good quality hitch pin with clip and safety chain.

SAFETY CHAIN USER INSTRUCTIONS

a) Secure the safety chain by looping it around the tongue support located on the underside of the outer
tongue. Extend the chain through the support located on the underside of the inner tongue and connect to
the towing machine’s attaching bar .
b) Be sure to run the safety chain through the support on the underside of the inner tongue. This will
provide an intermediate support for the safety chain.
c) Do Not allow more slack than necessary for articulation (max. 9 inches)
d) Do Not use any intermediate support as the attaching point.
e) Store the safety chain by securing it around the tongue support s.
f) Replace the safety chain if one or more links or end fittings are broken, stretched or otherwise damaged
or deformed.

Have all danger, warning, caution and import ant signs on the equipment been read and clearly understood? If
employees or others use or are near this equipment, make sure that they also have read and understood all
danger, warning caution and important signs on the equipment and have also read the operator’s manual.

Have the wheel bearings been inspected? Repack with grease if needed. Grease both the tongue bolt and the
hitch bolt.

750-16 OWNER’S MANUAL

Do not exceed the load limit of the unit.
BRAKING SYSTEM REQUIREMENTS:

Tow Loads Safely

Stopping dist ance increases with speed and weight of towed loads, and on slopes. T owed loads with or without
brakes that are too heavy for the tractor or are towed too fast can cause loss of control. Consider the total
weight of the equipment and its load.

Observe these recommended maximum road speeds, or local speed limits which may be lower:

If towed equipment does not have brakes, do not travel more than 32 km/h (20 mph) and do not tow
loads more than 1.5 times the tractor weight.

If towed equipment does have brakes, do not travel more than 40 km/h (25 mph) and do not tow
loads more than 4.5 times the tractor weight.

Ensure the load does not exceed the recommended weight ratio. Use additional caution when towing loads
under adverse surface conditions, when turning, and on inclines.

IMPORT ANT:

Keep the tires properly inflated. Both under inflation 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 hub caps are for between scheduled
service lubrication.

If equipped with disc brakes, inspect the brake pads 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 stored in a clean dry
place when not in use.

Adjusting the Drum Brakes

E

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

1

adjustment 18 to 20 notches.

Hydraulic Lines

F

Use care in shaping brake lines to avoid sharp bends
or kinks. Be sure and use a “Double Flaring” type of
tool on steel tubing to assure tight leakproof
connections. Be sure and use hydraulic rubber hoses
at points of flexing. Anchor hose ends to avoid stress
on tubing.
