KNOW YOUR MACHINE The following is a list of ten important safety precautions and warnings you should read through and understand before operating or servicing your machine. 1. Don't assume that because you know the control functions of other similar machinery, that you can run and/or service the Barko Loader.
Page 129: Safety Summary
SAFETY SUMMARY Failure to follow safety precautions in this manual can result in death, severe personal injury and/or property damage. Carefully read safety precautions below and within this manual. Heed all decals on machine. DANGER - Indicates an immediate hazard which WILL result in severe personal injury or death. WARNING - Indicates a hazard or unsafe practice which COULD result in severe personal injury or death.

Page 134: Fire Prevention
FIRE PREVENTION This machine may have several components which are at high temperatures under normal operating conditions, such as the engine, exhaust system, brake system and transmission. Clean the machine often. High pressure washing of the machine is suggested every 1000 hours (or 6 months) and always after a spill.
Page 135 LOADER MOUNTING INSTRUCTIONS Use these recommended procedures for mounting Back of Cab (BOC) and Trailer Mount (TRL MT) machines to truck or trailer frame. The truck frame is usually made of channel, while the trailer frame is usually made of -beam. These instructions show channel, however the principles for mounting to -beam are generally the same, unless noted.
Page 136 LOADER MOUNTING INSTRUCTIONS CONTINUED... NOTE: To prevent distortions of truck/trailer frame and ensure solid base for loader, align spacer blocks with edge of truck/trailer frame. ADDITIONAL SPACERS Additional spacers should be installed between loader frame and clamping plate around outside mounting studs. Spacers should be made from 3 x 4.1 lb.
Page 137 LOADER MOUNTING INSTRUCTIONS CONTINUED... Another means of securing spacer blocks to mounting studs is to drill two holes in each spacer block, fit spacer blocks into place on truck/trailer frame, and insert a "U" bolt around each mounting stud and through holes in each spacer block.

Page 148: Preventive Maintenance
PREVENTIVE MAINTENANCE Preventive maintenance is really just a simple matter of common sense. If you keep any piece of mechanical equipment clean and properly lubricated, and promptly replace any worn or damaged parts, you are going to "prevent" deterioration and promote long life and safe, productive service. The only other requisite to such a program is the regular scheduling of such maintenance.

Page 155: Hydraulic Filter Maintenance
HYDRAULIC FILTER MAINTENANCE Regular maintenance of filter elements is the key to clean fluid and long component life. Filters do not function when elements are clogged with contaminants to the point of bypass. NOTE: On a new machine the filter elements must be changed after the first 50 hours of operating time and then every 400 hours after that.

At the back of the valve, remove all bonnet assembly parts that are connected to the spool and keep them in the order of disassembly.
Page 159: Eliminating Air From The System
ELIMINATING AIR FROM THE SYSTEM All hydraulic fluid contains some dissolved air, usually about 10% by volume. Under increased pressure, the fluid will absorb much more air. Aeration in a hydraulic circuit is the presence of free air in places where there ought to be only fluid.
Page 160: Hydraulic Fittings, Hoses & Tubing
HYDRAULIC FITTINGS, HOSES & TUBING A heavy wall tubing and multi-wire hose network carries the hydraulic oil from the reservoir to the pumps and valves and then to cylinders and motors and finally back to the reservoir. Operating pressure of the hydraulic system varies from model to model. For your loader, consult the Hydraulic Pressure Warning Sheet in this manual.
Page 161: Hydraulic Cylinder Maintenance
HYDRAULIC CYLINDER MAINTENANCE Hydraulic cylinders provide force used to operate booms, attachment, and stabilizers. Proper maintenance of cylinders will promote long life and smooth operation. Inspect cylinders daily for leaks or damage and repair or replace as necessary. Lubricate cylinder grease fittings daily. Cylinder shown may not be type used on your machine but is shown as a reference.
