5.2 Lubrication
All bearings should be lubricated with a high quality high temperature grease . Shell Darina EP2
or compatible is required. Mixing grease types can lead to catastrophic failure. Many types of
grease bases (or soaps) are not compatible and can chemically react and fail. Lubricate bearings
monthly, or every 200 hours of operation.
5.3 Chest Adjustment
The chests are supported at each corner by two rollers (see figure 5.6 on page 45). The chests are
properly adusted at the factory and normally require no attention. The adjustment procedure is as
follows:
NOTE: Do not attempt adjustments on this machine if you are not trained and authorized to do
so. Follow all lockout and tagout procedures and remove power before servicing this machine.
1. Loosen transport bolts in longitudinal (front-to-back) direction only. The chests can now
move freely in one direction. Do not loosen the axial transport bolts at this time.
2. After the ironer has been at temperature for at least 6 hours, tighten the longitudinal bolts so
that a gap of about 2mm (.08”) remains and then tighten the lock nuts.
5.4 Drive Belt Adjustment
The transmission of power between the drive pulleys and the slip-on gear boxes for the rollers and
the in feed conveyor occurs by means of a high-performance V-belt system.
The proper adjustment of this V-belt system is an important aspect of avoiding abnormal wear of
the belts and to guarantee optimal power transmission. Excessive tensioning of the belts will cause
premature wear of the belts and bearings (caused by high radial forces). Insufficient tension will
cause premature wear of the belts and a slip between the rollers which will again cause disruption
of the procession between the rollers and generally poor ironing performance.
The tension of the belts can be adjusted by means of moving the drive motor frame and/or ad-
justing the tension pulleys. After the initial set-up, the belts are to be checked after 100 operating
hours.
The deflection force must always be measured perpendicular to the belt. The deflection is equal to
1 mm. per 100 mm. (i.e. – 1/8” per 1 foot) strand length.
The deflection force and the deflection can be easily checked with a tension tester that is available
from most auto parts stores. The tension tester consists of a calibrated spring measures on one side
