HOW TO FREE THE AUGER CABLE
IMPORTANT: If the auger cable will not move when you
ENGAGE the bail, the auger cable could be frozen in-
side the conduit. DO NOT pull on the auger cable.
Instead, thaw the conduit and lubricate the auger
cable.
1. Thaw the conduit so the auger cable moves freely.
2. Work grease into the opening on the top of the conduit
where the auger cable enters.
