MAINTENANCE:
Maintaining your mixer is not difficult if you follow these guidelines:
- Keep the mixer clean.
- Check all set-screws and fasteners, tighten as needed.
- Check all wiring on a regular basis and repair as needed.
- Air motor powered units:
• Keep air supply dry and oil in the lubricator.
Lubrication
BGF Series Models with Gear Reducers
- Winsmith 917 & 920 Series
Factory Filled:
Your new speed reducer is filled to the proper level for standard mounting position with the appropriate grade of oil for operation
in a 51°F to 110°F temperature environment. The oil level should be checked and adjusted (if necessary) prior to operation, using
the oil plug provided and while the unit is oriented in its operating position.
If operating ambient temperature is outside the range specified above, then refer to the lubrication chart and refill the unit with the
correct grade based on actual ambient temperatures.
Oil Changing:
When changing oil for any reason, it should be remembered that oils of various types may not be compatible. Therefore, when
changing to a different oil, it is recommended that the housing be completely drained and thoroughly flushed with a light flushing
oil prior to refilling with the appropriate lubricant. The oil level should be rechecked after a short period of operation and adjusted
if necessary.
Initial Oil Change:
The oil in a new speed reducer should be changed at the end of 250 hour of operation.
Subsequent Oil Changes:
Under normal conditions, after the initial oil change, the oil should be changed after every 2,500 hours of operation, or every six
months, whichever occurs first. Under severe conditions (rapid temperature changes, moist, dirty or corrosive environment) it
may be necessary to change oil at intervals of one to three months. Periodic examination of oil samples taken from the unit will
help establish the appropriate interval.
Synthetic Oils:
Synthetic lubricants can be advantageous over mineral oils in that they generally are more stable, have longer life, and operate
over a wider temperature range. These oils are appropriate for any application but are especially useful when units are subjected
to low start-up temperatures or high operating temperatures. However, continuous operation above 225°F may cause damage to
the seals or other components. It is recommended that the initial oil be changed or filtered after the first 1500 hours of operation
to remove metal particles that accumulate during break-in. Subsequent oil changes should be made after 5000 hours operation if
units are operating in a clean environment.
Oil Temperature:
Speed reducers in normal operation can generate temperature up to 200°F depending on the type of reducer and the severity of
the application (loading, duration of service, ambient temp.). Excessive temperature can result from overloading due to original
unit selection being too small for the application or increased load after original load size was selected. Overfilling and Under
filling the oil level of a speed reducer will cause overheating. Ensure oil is at the proper level.
