Instruction Manual

All standard IRONMAN BY OHIO GEAR™ Worm Reducers are factory filled with MOBIL SHC-634 lubricant, a synthesized hydrocarbon for-
mulated for long life and wide operating temperature range (-25°F to +220°F).
Change oil only when performing maintenance that requires gearbox disassembly.

If oil must be replaced, use only MOBIL SHC-634

Do not confuse MOBIL SHC-634 with MOBILGEAR 634. MOBILGEAR 634 is an EP type gear oil NOT suitable for use in the IRONMAN™
BY OHIO worm gear reducers.

SPECIAL LUBRICATION REQUIREMENTS - Size 830 & Larger
Please specify mounting position *with order* if any of the following applies:
1- Reducer is mounted with input or output shafts vertical
2- Input speed is less than 900 RPM
3- Reducer is mounted in inclined position
NOTE: The reducer may require modifications to assure proper lubrication in these applications.

The reducer is properly filled at the factory with sufficient lubricant per customer specified mounting position. If position is not specified by
customer, reducer will be filled to level in mounting position 1 (worm over) Reducer ordered with a "MOD" will be filled based on the factory
assumed mounting position, mounting position should be specified with order to assure proper lubrication.
