WARNING

Add air to the tires only in a safety cage. In-
spect safety cage for damage before use. When

adding air, use a clip-on chuck with enough
hose to let the operator stand clear of the cage.

NOTE:

When tightening the wheel nuts, DO NOT use

any lubricant on the studs or nuts.

13. Inflate the tires using a safety cage. Install the

wheels and nuts and tighten the nuts to 155 to
175 N•m (114 to 129 lbf ft).

14. Apply multipurpose grease with 2 to 4% molyb-

denum disulfide to new drain plug O-ring and in-
