SWIVEL JOINTS. The swivel joints (1, figure 3-2) are the side inlets to the hose reel and also are the
bearings for the hose reel drum. A grease fitting is installed on top of each swivel joint. Lubricate upon receipt of
equipment and at twelve month intervals with Molykote 33 or equivalent.

DRIVE BEARING AND BRAKE ASSEMBLY. A grease fitting is installed on the drive bearing housing (2,
figure 3-2) for lubrication of the chain drive shaft. Lubricate in accordance with item 1.
(3)
DRIVE CHAIN. The roller chain (3, figure 3-2) should be thoroughly cleaned before lubricating. Use a wire
brush and compressed air to remove accumulated dirt or grease. Lubricate thoroughly with SAE 30 engine oil, MIL-
02104 or equivalent, making sure the oil reaches the chain pins and rollers. Wipe off excess oil. Lubricate at monthly
intervals to minimize rust and corrosion when not in use.
