3. Maintenance
3.1. Routine Maintenance
Every 6 months
Check the security of all nuts and screws, and ensure all components are in a
serviceable condition and not damaged. Check that the mixer gearbox, electric motor
or air motor muffler are kept clean.
Visually inspect electrical components, cables, air lines for damage and rectify before
use. Electric motors do not require any internal maintenance and should be replaced if
a fault occurs.
Every 12 months
In-service inspection and testing of electrical equipment - Formally inspect and test
electrical components and cables in accordance with the portable appliance testing
(PAT) regulations in the UK, BGV A3 in Germany or local site codes of practice as
applicable.
3.2. Lubrication
Electric motor bearings are sealed for life, and do not require any maintenance or
re-lubrication.
The gearboxes are factory filled with Shell CASSIDA 220 food grade lubricant and
sealed for life.
Air line lubrication - use SAE #10 motor oil or equivalent for the air line lubrication.
3.3. Tightening Torques
Tighten all fasteners to values shown unless specifically instructed to do otherwise.
Lubricate all fasteners at assembly with grease, oil or an anti-seize material. Bolt threads
and contact surfaces of bolt heads and nuts should be lubricated.
The assembly on un-lubricated stainless steel fasteners cannot be recommended.

If fasteners cannot be lubricated, multiply table values by 1.25.
