Remove product from service before you perform the preventive maintenance inspection. At a minimum, check all items
listed during annual preventive maintenance for all Stryker Medical products. You may need to perform preventive
maintenance checks more frequently based on your level of product usage. Service only by qualified personnel.
CHECKLIST
____ All fasteners secure.
____ No cables worn, pinched, or frayed.
____ Replace siderail assist cable every five years.
____ Replace siderail central column spring every four years.
____ All plastic covers (including the base hood) intact. Replace if broken. Patient’s safety could be at stake if any
plastic cover is cracked, as sharp edges may be present.
____ Lubricate where required (see Maintenance Manual, figure 2.2, page 12).
____ Calibrate the scale (optional) once a year.
____ Review each function of the (optional) scale. Refer to the verification of the scale in the Setup Procedure
section (page 8). If the weight calibrated is out of the acceptable range (± 0.5 lb (0.2 kg) at 50 lb (22 kg) or
less or ± 1.0 lb (0.4 kg) at ≥ 50 lb (22 kg) when flat), immediately recalibrate the scale system (see section 3.7
of the Maintenance Manual, “Scale Calibration”).
____ Side/endrail handles trigger and rotating movement operates properly.
____ Side/endrails raise and lower smoothly, and lock in the 9 in., 14 in. and upper positions. If a siderail moves with
difficulty, remove the brake shoe cover and adjust the position of the stop catches. Refer to step 11 of the
“Central Column Assembly” replacement procedure, page 34 of the Maintenance Manual.
____ Side/endrails automatically stop at the 9 in. position when lowered without interruption (handle kept rotated to
the left or right while lowering the rail) from upper positions. Rotating the handle to the left or right further
