7 - MAINTENANCE
Clean in-line Diesel Exhaust Fluid (DEF) supply filter (Initial)
Clean the in-line supply filter when the machine is new and the hour meter registers 100 hours. Clean every 1500
hours thereafter or more often if conditions so require. The supply line has a small mesh filter within the line.
Prior operation:
Keep all unauthorized personnel clear of the area. Park the machine on level ground, in neutral with the parking
brake applied, and the attachment lowered to the ground. Make sure that all residual pressure is relieved from circuits
before beginning maintenance. Turn the electronic disconnect to the OFF position.
1. Open the rear left hand access compartment, and lo-
cate the DEF supply module.
