Before starting a job:
• Clean work area and machine.
• Make sure you have all necessary tools to do your job.
–UN–18OCT88
• Have the right parts on hand.
• Read all instructions thoroughly; do not attempt
shortcuts.

Service Machines Safely
Tie long hair behind your head. Do not wear a necktie,
scarf, loose clothing, or necklace when you work near
machine tools or moving parts. If these items were to get
caught, severe injury could result.
–UN–23AUG88
Remove rings and other jewelry to prevent electrical
shorts and entanglement in moving parts.

DX,LOOSE –19–04JUN90–1/1
Work In Ventilated Area
Engine exhaust fumes can cause sickness or death. If it is
necessary to run an engine in an enclosed area, remove
the exhaust fumes from the area with an exhaust pipe
extension.
–UN–23AUG88
If you do not have an exhaust pipe extension, open the
doors and get outside air into the area
TS220
DX,AIR –19–17FEB99–1/1
Illuminate Work Area Safely
Illuminate your work area adequately but safely. Use a
portable safety light for working inside or under the
machine. Make sure the bulb is enclosed by a wire cage.
The hot filament of an accidentally broken bulb can ignite
spilled fuel or oil.
