CAB INSTALLATION
BEFORE YOU START
HELPFUL REMINDERS:
A. Leave all bolts loose for later adjustment unless otherwise specified.
B. Read and understand all instructions before beginning.
C. Plastic washers have been supplied to provide a weather seal around
all exterior fasteners. The plastic washer should be installed under each
bolt head directly against the outside cab surface. Care should be taken
not to over tighten the fasteners and damage the plastic washer.
Also use metal washers as required.
D. Apply a clear silicone sealant to seal any minor gaps that may occur due
to vehicle variances. For example, windshield cowl to unitized frames.
