Refer to safety label page for label locations. Check tractor hydraulic fluid level. Refer to tractor operator’s manual...
Initial Lubrication perform service/maintenance Operations loader raised off ground. Lower the loader to the ground and relieve pressure in loader hydraulic lines prior to performing any service/maintenance operations on the tractor operating hydraulic control lever through all positions with engine off. Escaping fluid under pressure can have sufficient penetrate the skin, causing serious injury.
SET-UP INSTRUCTIONS After the machine has been completely assembled and lubricated, inspect it thoroughly certain it is operating properly before delivering it to the customer. The following checklist is a .reminder of points to inspect. Check off each item as it is found satisfactory adjustment is made.
OPERATION Precautionary Notes Do not lower the edge of the bucket too low for loading. Keep the bottom of the bucket level with the ground when loading. Do not use bucket for pushing down material with bucket cylinders partially extended. Damage cylinders may result.
OPERATION CONTROLLED RATE FUNCTIONS ‘By feathering (slightly moving) the control lever, precise operational speeds can be obtained. This action controls the position of the valve spools in the control valve and regulates flow of oil from/to cylinders. It is important to utilize this operational practice when lowerfng the main frame when the bucket is loaded with material.
LOADING Drive straight ahead into pile with bucket cutting edge level with the ground. In order to prevent possibility of damaging tractor or loader; Do not ram into pile at high speed. Do not attempt to turn tractor while loading. As bucket begins to fill with material, gradually roll the bucket back and raise the loader to increase “fill”...
OPERATION Transporting Material Transport material to “Unloading Point” with loader bucket as low as possible to prevent spillage maintain Tractor/Loader stability. During transport the loader should not be in a position that will impair operator’s vision. Safety: Avoid any overhead wires or obstacles when loader ls raised, to avoid damage or possible death by electrocution.
