Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.
Follow good shop practices.
- Keep service area clean and dry.
- Be sure electrical outlets and tools are properly grounded.
- Use adequate light for the job at hand.
Make sure there is plenty of ventilation. Never operate the engine of the towing vehicle in a closed building.
The exhaust fumes may cause asphyxiation.
Before working on this machine, drive to a level area, disengage the PTO, lower implement (or if working
underneath, raise and block securely), shut off the engine, set the brakes, and remove the ignition keys.
Be certain all moving parts on attachments have come to a complete stop before attempting to perform
maintenance.
Never work under equipment unless it is blocked securely. Never depend on hydraulic system to keep imple-
ment in raised position.
Always use personal protection devices such as eye, hand and hearing protectors, when performing any
service or maintenance.
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
Frequently check mower blades. They should be sharp, free of nicks and cracks and securely fastened.
Periodically tighten all bolts, nuts and screws and check that all cotter pins are properly installed to ensure unit
is in a safe condition.
When completing a maintenance or service function, make sure all safety shields and devices are installed
before placing unit in service.
Remove hydraulic pressure prior to doing any maintenance. Place the mower wings on the ground or securely
blocked up, disengage the PTO, and turn off the engine. Push and pull the remote cylinder lever in and out
several times to relieve hydraulic pressure.
Never use your hands to locate a hydraulic leak on attachments. Use a piece of cardboard or wood. Hydraulic
fluid escaping under pressure can penetrate the skin.
Openings in the skin and minor cuts are susceptible to infection from hydraulic fluid. If injured by escaping
hydraulic fluid, see a doctor at once. Gangrene and death can result. Without immediate medical
treatment, serious infection and reactions can occur.
