C: CAUTION
Please clearly understand and adhere to the following general precautions. They must be strictly followed to
avoid any injury to the person doing the work or people in the area.
1. OPERATION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Be careful not to burn yourself, because each part on the vehicle is hot after running.
•Use SUBARU genuine power steering fluid, grease etc. or the equivalent. Do not mix fluid, grease etc. with
that of another grade or from other manufacturers.
•Be sure to tighten fasteners including bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
•Before securing a part on a vise, place cushioning material such as wooden blocks, aluminum plate or
cloth between the part and the vise.
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 and local regulations concerning waste disposal.
