IMPORTANT SAFETY INFORMATION
Thoroughly read and understand the instructions given in this manual before operation. Refer to
the “Safety Label” section, read all instructions noted on them.
Do not allow anyone to operate this equipment who has not fully read and comprehended this
manual and who has not been properly trained in the safe operation of the equipment.
Operate equipment from the driver’s seat only and do not lubricate, adjust or repair when
machine is in motion.
Do not leave tractor or equipment unattended with engine running.
Do not allow anyone to stand between tractor and equipment while backing up to equipment.
Keep hands, feet, and clothing away from power-driven parts. Wear snug fitting clothing to avoid
entanglement with moving parts.
Do not carry passengers on equipment at any time.
Turning tractor too tight may cause equipment to ride up on wheels. This could result in injury or
equipment damage.
Dismounting from a moving tractor could cause serious injury or death.
Should hydraulic hoses and/or fitting be accidentally damaged, replace those components for safe
operation. Never open hydraulic components under pressure.
BE AWARE OF SIGNAL WORDS
A signal word designates a degree or level of hazard seriousness. The signal words are:
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious
injury. This signal word is limited to the most extreme situations, typically for machine
components that, for functional purposes, cannot be guarded.
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when guards are removed. It may also be used to
alert against unsafe practices.
CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe practices.

PREPARE FOR EMERGENCIES
Be prepared if a fire starts.
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital and fire department near phone.
SHUTDOWN AND STORAGE
Lower machine to ground, put tractor in park, turn off engine, and remove the key. Detach and
store implements in an area where children normally do not play. Secure equipment by using
blocks and supports.

DRAWBAR HOOK-UP
Keep the pull block on horizontal position tightening the fixing bolt. Be sure to loosen the bolt
before operating.
There are twenty-two different grease zerks on the machine; one on each cylinder pin; one on
each of the rear frame pivot pins; eight on the push gate; one on the ball and receiver; and one on
the swivel hitch.
The machine should be greased every four hours or daily, depending on usage.
The wheel bearings should be repacked yearly.
Check air pressure in all tires and kept at minimum of 50 lbs.
Lug bolts should be checked periodically. Refer to "Torque Values Chart" to determine correct
torque values when tightening hardware.
FIXING BOLT

12
OPERATION
The 1250 Carry All scrapers are designed with Category III and IV hitch. Horsepower rating of
tractor should be between 200 and 300 hp for the 1250 single and between 250 and 350 hp for
the 1250 tandem.
IMPORTANT: You could lose steering control if your tractor is too light. Refer to your tractor's
manual to determine if additional ballast is needed.
Follow all laws when transporting on highways and drive slowly over rough ground, side hills, and
around curves. Always put transport lock in while traveling down the road.
Watch out for wires, trees, etc., when raising equipment. Make sure all persons are clear of
working area.
Hook up to the tractor, cycle all hydraulics and be sure to remove transport locks by raising the
scraper with your hydraulics before operating.
Check the oil levels in the tractor hydraulic system and add to maintain the proper level. Care
should be used when adding oil or when disconnecting any oil line to keep all dirt out of the oil, as
dirt is a major factor in the failure of hydraulic components.
There are two sets of hydraulic controls: The two outside hoses control the raise and lower. The
two center hoses operate the clam and the pushgate. The clam will rise completely open, before
the pushgate cylinders start pushing, without closing the clam. You can level from 0 to 14 inches
by adjusting the height of your scraper and then pushing out your load.
Oil flows first to the clam’s cylinders until they are fully extended. Once the cylinders are fully
extended, the clam circuits’ hydraulic pressure begins to increase. Once the pressure threshold is
surpassed (which is adjustable. See adjustment section), the relief valve diverts the oil flow to the
pushgate’s hydraulic circuit. Once the push gate is completely extended the operator then
reverses the tractors hydraulic remote. The check valve allows the clam to close and the push gate
could be fully retracted.
SETTING THE VALVES

13
Remove acorn nut, loosen lock nut and turn adjustment screw counter-clockwise to increase
speed of the pushgate.
BLADES
Inspect cutting edges daily. Replace cutting edges when center blade has been worn to
approximately 4” and side edges worn to approximately 3”.
CAUTION
Failure to replace worn cutting edges may result in unnecessary wear to the earthmover sides and
floor.
Note: Please specify left or right cutting edges when ordering replacements. Left or right side parts
are determined by viewing from rear of the scraper.
When the scraper is placed into operation, the operator will have to “feel out” the amount of
depth of cut to obtain maximum loading efficiency. This is usually accomplished by taking a lesser
and more uniform cut; however, some soil conditions such as loose sand may require a “pumping
action” obtained by taking successive deep cuts and lifting out of cut as the tractor begins to lose
power or traction.
