Maintenance Manual

Maintenance Program

This manual has been prepared to assist you in maintaining your Proline Doors. A
regular maintenance program is the easiest way to ensure free operation of the Chase
Doors. Your program should include a regularly scheduled lubrication and cleaning
procedure.

Ÿ The doors and seals should be inspected visually.
Ÿ Gaskets should be checked for cuts and tears.
Ÿ Hinges should be securely fastened.
Ÿ The door should open and close freely.
Ÿ When closed the door should be centered in the opening.
Ÿ Double doors with gasket should also seal in the middle where the gaskets

touch
Ÿ Bumper, impact plates, kickplates and hinge adapters should be examined for

loose fasteneres

Our recommendation for lubrication and cleaning are as follows:

Hinge System:

Ÿ E Hinge - Remove hinge covers and wipe off old grease and apply new grease

(wheel bearing type grease). DO NOT OVER GREASE. Inspect for loose fasteners
and reinstall hinge cover. Repeat every six months

Ÿ V Cam - Lubricate upper and lower hinge shafts and cam roller area every 90 days

with silicone spray, or similar lightweight oil

E-Hinge V-Cam Hinge

Door Panel and Gaskets:

Ÿ Using a sponge or cloth wash door panel and gaskets with dishwashing

detergent, mixed with water 1/50. DO NOT USE ANY TYPE OF SPRAY
CLEANER, ACETONES, CHLORINATED SOLVENTS OR OTHER CHEMICALS OF
THIS TYPE. Dry and apply a plastic treatment, such as ARMOR-ALL, to the gaskets.

Window Cleaning:

Ÿ Wash the window area with a mild soap or an all purpose glass cleaner and

dry with a soft cloth. Do not use solvents, bleach or petroleum products on windows.

Trouble shooting procedure for general problems

As with any product designed for impact, Chase Doors will suffer some wear and tear
over years of use. We have developed a trouble shooting procedure to help identify the
most common problems and repair directions to assist in returning the door to
operational condition. It is important in following the trouble shooting procedures, that
accurate measurements be taken when there is a need to call the factory.
