Maintenance
!CAUTION
BEFORE any maintenance is performed, lower the Powered Rake to the ground, stop tractor engine and remove key. DO NOT attempt to make maintenance adjustments while tractor is running.
IMPORTANT: Proper servicing and adjustment is the key to the long life of any machine. With careful and systematic inspection of the Powered Rake, costly maintenance, time and repair can be avoided.
Storage
At the end of the working season or when the Powered Rake will not be used for a long period, it is good practice to clean off any dirt or grease that may have accumulated on any of the moving parts.
Check the roller studs or bars for wear and replace the roller and/or studs if necessary.
Inspect the Powered Rake for loose, damaged or worn parts and adjust or replace if needed.
Lubricate as noted in “Lubrication” on page 14.
