Removing the Blower/Chipper Engine Unit
•
BEFORE PERFORMING ANY MAINTENANCE, SHUT OFF THE ENGINE, ALLOW FIVE (5) MINUTES
FOR PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE.
•
BEFORE PERFORMING THIS PROCEDURE, ENSURE THAT YOUR DR LEAF AND LAWN VACUUM IS
ON LEVEL TERRAIN AND THE BRAKE IS SET ON YOUR LAWN TRACTOR.
•
FOR THE SUBARU ENGINE MODEL, YOU WILL NEED AN EXTRA PERSON FOR LIFTING THE ENGINE.
•
DO NOT USE CHIPPER OR VACUUM FEATURES WITHOUT FIRST SECURING THE ENGINE TO THE
FRAME AND SECURING THE HOSES.
1. Disconnect the Blower Exit Elbow Assembly from the Collector Box Hose (Figure 45 on page 42).
2. - For the B&S Engine model, lower the three (3) Frame Support Legs by removing the Safety Hitch
Pins (Figure 18 on page 20). When you lower the Legs, re-install the Safety Hitch Pins.
- For the Subaru Engine model, remove the Safety Hitch Pin and raise the Caster Wheel, then re-
install the Safety Hitch Pin (Figure 5
on page 14).
3. Remove the Hitch Clip from the Clevis Pin and remove the Pin (Figure 19 on page 20). Move the
Trailer Tongue from the Tractor Hitch Plate in a side motion. For the Subaru model, you can now
set the Trailer Tongue on the ground.
