9. Maintenance

The SC3 and SC4 require very little maintenance. Inspect
them regularly for signs of wear or damage. If necessary,
replace any worn or damaged components before
attempting to use the chuck.
Depending on the amount of use, both chucks may
require occasional cleaning, particularly the SC3 which
has an open back. Regularly check the gear to the rear
of the SC3 for dust and debris, cleaning if necessary, as
described below.
The SC4’s backing plate protects the gear and pinions
from dust and debris but over time fine dust may
accumulate around them. To prevent this happening, it
is advisable to inspect the chuck occasionally and clean
if necessary.
Please note: If either the SC3 or SC4’s gears
become stiff and difficult to turn this will most
likely be due to the accumulation of dust and
debris. It is advisable to clean the chucks to
resolve this problem. If the problem is still
present after cleaning then please contact
Record Power customer services in your country.
Cleaning the SC3
Remove the circlip which holds the scroll gear in the
chuck body using a pair of circlip pliers as shown in Fig
9.1.
Warning: Wear eye protection when removing
the circlip as it may fly from the pliers.
Carefully turn the chuck body to face upwards. This will
allow the scroll gear to drop from the chuck body. Ensure
it is caught to prevent any damage, Fig 9.2.
Remove all 4 jaw slides as shown in Fig 9.3 by carefully
pulling them away from the chuck body.
Once the chuck is fully disassembled, remove all grease,
dust and debris from the components.
Once clean, apply a generous amount of fresh standard
multi-purpose grease to the scroll gear before re-
assembling the chuck.
