General Maintenance
?
It is recommended that the following checks and adjustments are carried out at
minimum of twice a year and more frequently if the couch is in constant use.
?
The framework of the couch is of steel construction and coated
with an epoxy paint finish. This is resistant to most cleaning
substances.
?
The major pivot points need to be lubricated sparingly with oil.
Care should be taken to keep oil away from the upholstery.
?
All nuts should be checked and tightened where necessary.
Care should be taken not to over tighten the nuts on the pivot
points as this may cause them to bind.
?
Air tubes should be checked to ensure that they are not
pinched.
?
Disconnect the mains supply and check the following;
NOTE - all electrical checks should be carried out by a suitably
qualified person.
Electric cables and mains plug should be inspected for damage
and replaced where necessary. In addition, electrical safety
checks for earth continuity (class I equipment only) and earth
leakage checks should also be carried out.
The correct value fuse of 5 amps and ASTA approved to
BS1362 MUST be used.
?
The upholstered top is manufactured using fire retardant vinyl.
This tends to go brittle if oil or grease (including body oils) are
left on it. The upholstery should be cleaned with warm soapy
water after use. The use of detergents is not recommended
although a suitable sterilization fluid is acceptable. Use of a
couch cover or towel will help prolong the life of the upholstery
.
?
Woodscrews, used to secure the upholstery, should be checked
and tightened or replaced where necessary.
?
The hinge pins on the head and foot sections should be
checked to ensure that they have not moved within the hinge
tubes. If the pin protrudes, a heavy tap with a hammer should
be required to relocate it. If the pin moves easily, the knurling
may be insufficient to hold the hinge pin in place and a new pin
must be fitted.
