Maintenance
Winterizing for Storage
Perform the following procedures to prepare the
machine for winterizing and storage.
1. Store the machine in a dry, protected area:
• Cover seat with plastic. Place a “DO NOT
OPERATE” tag on the main control panel.
• Cover all exposed control panels with tarps or
plastic.
• Ensure all cab doors and windows are closed
and seal properly.
• Ensure the tires are properly inated.
• Replace worn or damaged decals if needed.
2. Inspect the machine thoroughly and repair worn or
damaged parts. Inspect all hoses, couplers, ttings
and cylinders. Tighten loose ttings and replace any
worn hoses found.
3. Lubricate all grease points:
• Coat all exposed cylinder shafts with lithium-
based grease.
• Ensure all exposed threads are lubricated.
• Ensure cables are lubricated and move freely.
• If the machine has high- and low-speed chains,
be sure they are oiled.
4. Check air lter. Clean or replace air lter elements if
needed.
5. Check engine oil level and ll if needed.
• Drain dirty engine oil, ll with new oil and run the
engine ve minutes to allow the oil to penetrate
components.
To avoid the danger of exhaust fume
poisoning, DO NOT operate the engine in a closed
building without proper ventilation. Check hydraulic
oil sight gauge and ll if needed.
Hydraulic oil that is contaminated
must be drained, the lter elements replaced and
the hydraulic tank relled. Failure to perform this
maintenance procedure if needed could result in
premature failure of the pumps or motors.
