Keep Mechanical Registers Lubricated
Although the mechanical registers used in GASBOY pumps are carefully adjusted and lubricated
at the factory before shipment, they require (as do all mechanical parts) occasional cleaning and
lubrication when in service. The intervals at which this should be done vary with conditions of
operation, but under normal conditions it is necessary only twice a year, or after each 100,000
gallons delivered.
Clean the mechanical register with compressed air* and wipe all accessible parts (such as figure
wheel drums) with a clean cloth. Never use solvents, such as gasoline or kerosene, as this will
become trapped in many of the inaccessible bearings and dissolve the new lubricant when it is
applied.
A light, non-acid type oil (SAE 10) is recommended because this gives maximum protection in
varying temperatures. The oil must also be acid-free so that it will not cause corrosion of the cast
metal parts. A long handled, fine lettering brush is very convenient for applying the oil to all
bearings and shafts and for applying light, nonfluid oil (grease with body similar to that of chassis
lubricant) to the bevel type gears.
NOTE: Always wear protective safety goggles or glasses when using compressed air.
Dial Face
Clean the dial face with a soft, clean, damp cloth as often as necessary.
Cleaning the Strainer
Clean the strainer immediately after the pump has been installed and tested, and again after a few
hundred gallons have been delivered. Thereafter, once every six months, or as required.
The symptoms of a dirty or clogged strainer in a pump are slow delivery, noisy operation, and
pulsation. To clean the strainer, turn off AC power to the pump. Locate the Suction Strainer Cap
on the plumbing unit and unscrew it to access and remove the strainer. Use compressed air* to
blow the dirt out of the strainer.
NOTE: Always wear protective safety goggles or glasses when using compressed air.
Filter
If the unit is equipped with a filter, check and change it at regular intervals. A dirty filter in a
pump or remote dispenser will cause a slower delivery rate. Refer to the accessories section of
your parts manual to ensure that you replace the filter with one designed for your model. Always
use a drip pan directly below the filter when removing the cartridge to prevent contamination of
both the soil and the electrical components within the cabinet.
Adjusting the Belts
With the proper care, belts will give exceptionally good service. A loose belt not only cuts down
dispensing speed, due to slipping, but also results in excessive wear. A properly tightened belt
will allow twisting the belt 180 degrees midway between the motor and the pump pulleys.
On the 9122Q and 9123Q models, the belt can be tightened by loosening the cap screw which
holds the idler arm and sliding the arm to obtain the correct belt tension of 6 3/4 lbs (+ 3/4). When
the adjustment is complete, remember to retighten the cap screw.
