3. PRE-OPERATION INSTRUCTIONS

IMPORTANT: Do not extend bucket cylinders without quick draw latch attach installed on loader. Failure to follow these instructions could cause attachment cylinder damage and will void loader warranty.

TRANSMISSION FLUID

Check the tractor hydraulic fluid level and fill, if required.

INITIAL LOADER OPERATION

NOTE: Keep engine speed at low idle during the initial loader operation.

CAUTION

ESCAPING HYDRAULIC FLUID UNDER PRESSURE CAN HAVE SUFFICIENT FORCE TO PENETRATE SKIN, CAUSING SERIOUS PERSONAL INJURY. BEFORE DISCONNECT- ING LINES, BE SURE TO RELIEVE ALL PRESSURE.

BEFORE APPLYING PRESSURE TO SYS- TEM, BE SURE ALL CONNECTIONS ARE TIGHT AND THAT LINES, TUBES AND HOSES ARE NOT DAMAGED.

FLUID ESCAPING FROM A VERY SMALL HOLE CAN BE ALMOST INVISIBLE. USE A PIECE OF CARDBOARD OR WOOD, RATHER THAN HANDS, TO SEARCH FOR SUSPECT- ED LEAKS.

IF INJURED BY ESCAPING FLUID, SEE A DOCTOR AT ONCE. SERIOUS INFECTION OR REACTION CAN DEVELOP IF PROPER MEDICAL TREATMENT IS NOT ADMINIS- TERED IMMEDIATELY. REFER TO FIGURE 1.

IMPORTANT: Contaminants in hydraulic fluid can cause valve spools to stick. BE ALERT when operating loader and follow your tractor Operator Manual hydraulic fluid maintenance schedule.
