Handle Chemical Products Safely

Direct exposure to hazardous chemicals can cause
serious injury. Potentially hazardous chemicals used with
John Deere equipment include such items as lubricants,
coolants, paints, and adhesives.

A Material Safety Data Sheet (MSDS) provides specific
details on chemical products: physical and health hazards,
safety procedures, and emergency response techniques.
Check the MSDS before you start any job using a
hazardous chemical. That way you will know exactly what
the risks are and how to do the job safely. Then follow
procedures and recommended equipment.

Prepare work site properly. Avoid operating near
structures or objects that could fall onto the machine. Clear

loads over or near bystanders. Use barricades or a signal
person to keep vehicles and pedestrians away. Use a
signal person if moving machine in congested areas or
where visibility is restricted. Always keep signal person in
view. Coordinate hand signals before starting machine.
Work Site Hazards
Operate only on solid footing with strength sufficient to
support machine. When working close to an excavation,
position travel motors away from the hole.
Reduce machine speed when operating with tool on or

T133549 —UN—24AUG00

Clean Exhaust Filter Safely

During exhaust filter cleaning operations, the engine
may run at elevated idle and hot temperatures for an
extended period of time. Exhaust gases and exhaust
filter components reach temperatures hot enough to burn
people, or ignite or melt common materials.

TS227 —UN—15APR13
Keep machine away from people, animals, or structures
which may be susceptible to harm or damage from hot
exhaust gases or components. Avoid potential fire or
explosion hazards from flammable materials and vapors
near the exhaust. Keep exhaust outlet away from people
and anything that can melt, burn, or explode.
Closely monitor machine and surrounding area for
smoldering debris during and after exhaust filter cleaning.
Adding fuel while an engine is running can create a fire
or explosion hazard. Always stop engine before refueling
machine and clean up any spilled fuel.

TS271 —UN—23AUG88
Always make sure that engine is stopped while hauling
machine on a truck or trailer.
Contact with exhaust components while still hot can result
in serious personal injury.
Avoid contact with these components until cooled to safe
temperatures.
If service procedure requires engine to be running:
• Only engage power-driven parts required by service
procedure
• Ensure that other people are clear of operator station
and machine

TS1693 —UN—09DEC09
Keep hands, feet, and clothing away from power-driven

pressure lines and “light” for return lines.
Some “heavy” and “light” sizes can be threaded
together but do not seal properly. Be sure not
to mix “heavy” and “light” fittings.

1. Inspect the fitting sealing surfaces. They must be free

of dirt scratches, nicks, and burrs.
2. Inspect the O-ring. It must be free dirt, cuts, cracks, Hold connections together while tightening nut to

3. Lubricate O-rings using a thin film of clean hydraulic oil. 5. Tighten nut (A) hand tight so O-ring contacts seat and
then an additional 1/4—1/3 turn using a wrench.
4. Align an adjustable fitting with the tube.
