WARNING
1. This equipment must not be operated without proper guarding of
all moving parts. While performing maintenance be sure remote
power switches are locked off. See installation manual for recom-
mended safety practices.
2. Before starting: Check all setscrews for tightness and rotate wheel
by hand to make sure it has not moved in transit.
* Suggested lubrication interval under ideal continuous operating con-
ditions. Relubricate while running, if safety permits, until some purging
occurs at seals. Adjust lubrication frequency depending on conditions
of purged grease. Use one-half of listed interval for vertical shaft appli-
cations or for 24 hour operation. Hours of operation, temperature, and
surrounding conditions will affect the relubrication frequency required.
1. Lubricate with a high quality NLGI No. 2 lithium-base grease hav-
ing rust inhibitors and antioxidant additives, and a minimum oil
viscosity of 500 SUS at 100°F (38°C). Some greases having these
properties are:
Shell - Gadus S2 V100 2
Exxon - Ronex MP
Mobil - Mobilith SHC100
Mobil - Mobilith SHC220
2. Lubricate bearings prior to extended shutdown or storage and
rotate shaft monthly to aid corrosion protection.
