PREVENTIVE MAINTENANCE
The information presented below can save you time and trouble, and if adhered to, will prolong
the service and life of the Weighmobile.
1. Do not lift the boom by hand. Use only the pump.
2. A small amount of oil will accumulate around the piston from time to time. This should be
removed with a facial tissue.
3. Casters and axle bolts require inspection every sixty (60) days to be sure that the axle nuts
are tight and that the casters swivel and roll smoothly. A light grease (waterproof auto
lubricant) may be applied to the ball bearing swivel of the casters once a year, or more
frequently if the casters are exposed to extreme moisture conditions.
4. The hydraulic pump is factory sealed. If service is ever required, the pump unit must be
returned to the factory for repair. This is seldom necessary, but after many years of service,
the seals may require replacement. Do not attempt to open the hydraulic pump to obtain
local service. This will void the guarantee, and may result in damage and costly repair.
5. Periodically check and tighten all bolted connections and check that both "U" bolts are
securely fastened to the boom assembly.
IMPORTANT! Failure to maintain tightness of bolted connections may result in
injury to the patient and/or Weighmobile operator.
7. When transporting the Weighmobile between locations, use care in observing clearance
through doorways, etc. Severe collisions with the weighing assembly could result in
permanent damage to the weighing sensors. Also, when moving the Weighmobile through
doorways and corridors, insure that the stretcher is stored in the stretcher transport carrier.
NOTE: The lower eyebolts are secured by a special type of locknut and must
NOT be tightened or adjusted. Tightening will preload the weight sensor and
result in inaccurate readings or possible permanent damage.
SERVICE INFORMATION
The Detecto Weighmobile is designed and fabricated as a precision scale instrument. It is
comprised of four (4) major subassemblies that are functionally integrated and are most
efficiently serviced as a system or independently at the factory. In the event that factory repairs
are required, call the factory for service authorization. It is suggested that the inoperative
subassembly be tagged with a manila tag, bearing as much information as possible regarding
the nature of the problem. Refer to Operation Manual 8555-M167-O1 for questions regarding
the 758C indicator.
PROBLEM
SOLUTION
Weights grossly inaccurate.
Make sure patient is centered on stretcher and not
touching any part of the bed or mattress.
Display does not illuminate, or turns off soon
after being turned on.
Batteries may be discharged. If using Alkaline,
remove and replace. If using Ni-Cad or NiMH
batteries remove and recharge in external charger.
Weight reading does not change when applying
weight to stretcher or force to ends of support
cage.
Make certain coiled cable from boom is plugged into
connector on indicator and screws are tight.
Instrument is defective. Call factory for assistance.
Instrument reading drifts randomly.
Call factory for assistance.
Certain segments of the display do not illuminate. Call factory for assistance.
Display is "locked up" - either over range or
underrange.
This is usually due to weight transducer or cable
malfunction, and is difficult to resolve without special
equipment. Call factory for assistance.
