Maintenance
Lubrication
Each unit has (3) grease fittings that must be lubricated
regularly with No. 2 General Purpose Lithium Base Grease.
1. The grease fitting locations and quantities are: reel
bearings (2) and carrier frame (1).
Note: Lubricate only one reel bearing fitting on each end.
Important
Lubricating immediately after washing
helps purge water out of bearings and increases bearing
life.
2. Wipe each grease fitting with a clean rag.
3. Apply grease until clean grease is detected around seal
guard of reel and pivot pin.
4. Wipe excess grease away.
