always be at least two people working together if the engine must be run

during service.

tools could break or slip, causing injury, or they may not adequately

perform intended functions.

• Unless necessary for servicing the engine, do not open the engine cover

while the engine is running.

contribute to unsafe operating conditions.

• Only tow the machine as described in this manual. See “Towing the

Loader” on page 94.

filler cap.

- Hydraulic system hoses, especially the pump outlet lines. Replace

hydraulic hoses every 6 years from the date of manufacture (month or

quarter, and year) is indicated on the hydraulic hoses.

• Keep mounting brackets and hose and cable routing straps tight. Hose

routing should have gradual bends.

• After cleaning the machine, examine all fuel, lubricant and hydraulic oil

lines for leaks, chafe marks and damage. Tighten any loose connections

and repair or replace parts as necessary.

• When handling oil, grease and other chemical substances, follow the

product-related safety requirements Material Safety Data Sheet (MSDS)

carefully to prevent burning or scalding.

• Do not use the machine in an environment where the hot muffler could

present a fire hazard, such as hay or straw storage facilities.

from the negative battery terminal, before performing electrical service or

electrical welding on the machine. See “Engine Start” on page 67.
