SAFETY
Improper use of a loader can cause serious injury or death. The following safety precautions, and those
given on the tractor mount installation instructions, should be thoroughly understood before attempting to
operate this machine.
BEFORE OPERATING:
Carefully study and understand this manual, the specific tractor mount instructions, and the
attachment(s) manual(s).
Prior to operation, inspect the loader for system leaks and damaged, missing, or malfunctioning
components in an effort to avoid the possibility of a dangerous failure involving structural
members or hydraulic system components.
Be certain any repairs necessary are completed prior to loader operation.
Follow recommended maintenance procedures and precautions on Page 12.
Completely familiarize yourself and others involved with the operation of the hydraulic control
valve before operating the loader.
Be certain all bystanders are clear of the machine and operation area prior to operation.
It may be necessary to add wheel ballast or rear weights as recommended by the tractor
manufacturer to maintain stability of the machine to prevent tipping or upset which could result in
serious injury or death. See mounting instructions for specific information.
It is recommended that both front and rear wheel treads be set to the widest recommended width to
prevent tipping or upset which could result in serious injury or death.
This loader is designed for farm type operations such as snow removal, barn and feedlot cleaning,
light commercial or light grading and digging. Its design is NOT intended for industrial use.
DURING OPERATION:
Never operate the machine other than from the tractor operator’s seat.
Be sure operating area is clear of others during machine operations.
Never lift, hoist, or carry humans in the bucket or on any portion of the loader or loader
attachments. Failure to heed, may result in serious injury or death.
Page 3
Transport the machine load at the slowest speed possible and with the loader boom at the lowest
transport position to avoid tipping or upsetting, which may result in serious injury or death.
Be extremely careful when working on inclines or near loose fill, rocks, and holes as they can cause
tipping or upsetting which may result in serious injury or death.
Be certain to avoid overhead electrical wires when operating loader. Contact with power lines may
cause serious injury or death.
Avoid sudden stops when lowering or lifting the loader boom to prevent loss of control over the
machine and/or load, which may result in serious injury or death.
Use maximum ballast and the widest recommended wheel setting on your tractor when handling
large shiftable loads.
Never attempt to ram with the bucket at high speed or full tractor power. Sudden impact may result
in structural failure and possible serious injury or death.
Never adjust or perform maintenance on the loader or tractor with the unit in motion, or without
power source locked out.
Never get under bucket or lift arms or reach through the lift arms or bucket linkage when the loader
is in operation. Inadvertent movement may cause serious injury or death.
FOLLOWING OPERATION:
Whenever the machine is not in operation, lower the loader boom and set the tractor brakes, disengage
drive, shut the engine off, and remove the ignition key before dismounting the tractor.
If loader is to be disengaged from tractor, be sure the loader is securely supported on a hard, level
surface and that the stand is securely engaged. Be certain all connections between tractor and
loader are free before disengaging.
TRANSPORTING:
Use safety lights and SMV emblem in addition to whatever local codes require when equipment is
being transported on the road or highway. Check with proper authorities for legal limitations.
Transport all loads at a slow and safe speed.
Carry the load as low as possible and maintain adequate visibility and good round clearance at all
times.

PERFORMING MAINTENANCE:
Carefully review, understand, and follow the “maintenance” section in this owners manual before
attempting to service loader.
Lower the bucket or attachment to the ground, shut off tractor engine, and relieve pressure in the
hydraulic system before adjusting, lubricating, or servicing the loader.
Escaping hydraulic oil under pressure can penetrate the skin. Never use any part of your body to
check for hydraulic leaks. Use cardboard when checking for leaks. See Fig. 1-1. Relieve hydrau-
lic pressure before disconnecting any hydraulic line. Failure to heed may result in serious injury or
death.
Before disconnecting hydraulic lines, lower the loader and attachments. Lock out the hydraulic
supply and relieve all hydraulic pressure.
Replace any damaged or painted-over decals. See Page 6 for replacement decals.
REMEMBER:
1. Move Slowly!
2. Always use care and common sense!
3. Be careful for your own sake and for that of others!
4. Koyker Mfg. Co. includes all reasonable means for accident prevention except a safe and
careful operator.

TRACTOR & SAFETY POINTERS
Page 7
The use of good judgment and common sense is necessary by the operator in using this loader. The front and
rear wheels should be set for the widest wheel tread to assure best stability. Use extra caution when rear
wheel weights and tire ballast are added to a loader-equipped tractor. DO NOT ram into frozen dirt piles,
frozen manure piles, ice, etc., with great momentum where sudden shock loads are encountered. Serious and
costly damage may result to both the loader and the tractor.
When scraping or back dragging do not extend the attachment cylinders more than one half of the cylinder’s
stroke. A limited amount of leveling may be done, when the loader valving is arranged with a float control.
This will prevent damage to cylinder rods. Never ride in the bucket.
Before operating the loader, be sure no one is standing near it. Only one person, the operator, should be on
the tractor. Remain at the controls and under no circumstances leave the tractor unattended with the bucket
in a raised position.
Never lift a person in the bucket or walk under a raised bucket.
Never drive your loader-equipped tractor down a hill that is steeper than 15 degrees. Carry all loads low and
use care on side hills.
Always keep unused PTO shaft clutch levers disengaged.
Keep hands, feet, and clothing away from all moving parts.
Hydraulic oil, under pressure, can cause injury. Be sure that all connections are tight and that all pressure is
relieved before disconnecting any lines.
Care must be taken with your loader cylinders. Nicks, scratches, rust, or other shaft damage can result in
worn packing causing cylinder leakage and subnormal performance.
