C: CAUTION
Please understand and adhere to the following general precautions. They must be strictly followed to avoid
any injury to the person performing the work or persons in the area.
1. OPERATION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Before disposing of shock absorbers, be sure to bleed the gas out completely. Also, do not expose to
flames or fire.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Use SUBARU genuine grease etc. or equivalent. Do not mix grease etc. with that of another grade or from
other manufacturers.
•Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or cloth
between the part and the vise.
•Be sure to tighten fasteners including bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
2. OIL
When handling oil, follow the rules below to prevent unexpected accidents.
•Prepare container and waste cloths when performing work which oil could possibly spill. If oil spills, wipe
it off immediately to prevent from penetrating into floor or flowing outside, for environmental protection.
•Follow all government regulations concerning disposal of refuse when disposing.
