Ikelite 6146.05 Instruction Manual page 24

Control Maintenance - continued
Some of the controls have long shafts and feature a hex style control gland.
-
These controls can be pulled out, exposing the shaft, Diagram K, page 25.
To lubricate the control, gently pull on the knob until the stainless steel
shaft is exposed. Lightly lubricate the shaft, then move the shaft in and out
several times. This will lubricate the x-ring in the Ikelite control gland. This
should be done before using the housing after a prolonged storage period,
or once a week when the housing is in constant use.
- Some of the controls have a short shaft and cannot be pulled out exposing
the shaft for lubrication. In the unlikely event one of these controls sticks or
becomes difficult to operate you can remove the control from the housing
and lubricate it, or return the housing to Ikelite for maintenance. To remove
the control, Diagram L, page 25, loosen the set screw in the knob (hex
head wrench required); remove the knob. If there is salt or dirt build-up on
the exposed control shaft, clean the shaft. Open the housing and gently
slide the control shaft out of the control gland. Clean and lightly lubricate
the shaft, including the end of the shaft. Slide the shaft back into the control
gland and gently slide the shaft back and forth a few times without fully
removing the shaft from the gland. Replace the knob noting the flat area
on the shaft. The set screw in the knob should tighten down against the flat
area on the control, so the knob does not turn on the shaft.
Close housing without a camera inside and water pressure test in a
bathtub or swimming pool. Rotate* the knobs to make sure the housing is
watertight and the gland was installed properly. Check all controls while the
housing is submerged.
*Caution: If your housing has a shutter spring, DO NOT rotate the shutter
control more than 1/16th of a rotation, otherwise, you may accidentally bend
the shutter spring or cause the spring to "pop off" the control shaft.
