Bloom Manufacturing LS12H Series - Manual (Page 6)

(d) Recommended Gear Oil:
Use BLOOM ULLTRA-LUBE NO. 601 trans-worm gear oil; available from Bloom in pints or quarts. For emergency
situations when BLOOM ULLTRA-LUBE NO. 601 is not immediately available, use Phillips 66 Company SAE grade
80W90 superior multi-purpose gear oil (Phillips 80W90 SMP) meeting API classification GL-5 or equivalent brand.
Continuous use of oil other than BLOOM ULLTRA-LUBE NO. 601 or Phillips 80W90 SMP oil may shorten the life of the
gears. DO NOT mix BLOOM #601 or Phillips 80W90 SMP with more than 50% of any other kind of oil.

high speeds when performing this operation.
• Make sure that the cable is unrolled in a line (to prevent kinks) and slowly inhaul the
winch to install the cable.
• Do not exceed one half rated load or one half rated line speed for the first thirty
minutes of operation. This will ensure that the worm and gear have an opportunity to
wear in properly.
