TIRE MAINTENANCE MANUAL - Goodyear Off-The-Road (OTR)

Be sure tool is properly seated. If not
properly seated it can fly off with great
force. Always stand away from tool when
it is under pressure.
4. Stand away from assembly and activate
hydraulic pump to apply pressure. If
necessary, release pressure and readjust
ram adjusting screw. Depress flange
1/2” - 3/4” (13-19 mm). Use a screwdriver
to slip a nut (or similar object)
between flange and lip of beat seat.
Keep fingers clear at all times.
Release pressure slowly. Check to make
sure the nut (or other spacer) will not
slip out. If not securely positioned, it
can become a projectile and cause serious
injury.
5. Move tool 2-feet around rim for second
bite.
Do not use tool near flange butt weld.
