🛠️ Service Notes

• Special tools are matched to particular engine and drive families — check the tool against the procedure in the workshop manual for your engine before ordering, as an almost-right tool will damage what it touches
• Use the tool only for the operation it was designed for, and do not add bars, extensions or leverage to make it reach further or pull harder than intended
• Inspect before every use and retire anything cracked, bent, spread at the jaws or worn in the threads rather than persevering with it
• Clean, dry and lightly oil the tool after use and store it where the working faces cannot be knocked out of true
