Daily Inspection
1.
If the OPTIMUS lift is equipped with an accordion bellows skirt, lift the bottom of the bellows skirt and secure it in the raised maintenance
position with the maintenance ties.
2.
ALWAYS engage the maintenance bars and ensure the scissors mechanism is securely blocked in the raised position before performing
ANY lift inspection or maintenance.
3.
Before use, visually inspect the lift for worn, damaged or broken components. If any of these conditions exist, REMOVE the lift from
service and contact a qualifi ed service person.
4.
Raise the platform and visually inspect the hydraulic components (i.e. pump, hoses, fi tting and cylinders) for oil leakage. If oil leakage
exists, REMOVE the lift from service and contact a qualifi ed service person.
5.
Check the condition of the warning labels. The warning labels are for the safety of the operator. If the labels are worn, missing or
unreadable, REPLACE them before placing the lift back in service.
6.
Finally, raise the lift and disengage the maintenance bars by returning them to their stored position.
Monthly Inspection and Maintenance
1.
If the OPTIMUS lift is equipped with an accordion bellows skirt, lift the bottom of the bellows skirt and secure it in the raised maintenance
position with the maintenance ties.
2.
ALWAYS engage the maintenance bars and ensure the scissors mechanism is securely blocked in the raised position before performing
ANY lift inspection or maintenance.
3.
Inspect snap rings and roll pins at all pivot shaft and axle locations. If not in place and/or secure, replace or repair at once.
4.
Inspect the scissors rollers, cylinder pivot pins, cylinder bushings, scissors pivot pins and scissors bushings for signs of wear. If worn,
replace at once. All pivot locations have lifetime lubricated bushings; therefore they do not need grease or lubrication.
5.
Inspect the hydraulic power unit and cylinder(s) for signs of leakage. The presence of a small amount of fl uid around the cylinder rod is
normal. However, fl uid fl owing from around the top of the cylinder head cap indicates worn seals. Replace the cylinder seals at once.
6. Inspect
the
fl exible hydraulic lines for chaffi ng and sign of wear. If worn, replace at once.
7.
Inspect the hydraulic line connections for tightness. Tighten if necessary.
8.
Check the level and appearance of the hydraulic fl uid. To do so, raise the unloaded platform and engage the maintenance bars. All
OPTIMUS lifts are equipped with translucent plastic reservoirs making it possible to visually determine the fl uid level without opening the
reservoir cap. The proper fl uid level is the lift on the maintenance bars. If required, add oil to the reservoir. Next, remove the reservoir
breather and check the condition of the oil, it should appear light in color. The oil should be changed if the color has darkened or if the oil
feels gritty. Obtain an oil sample to feel between your fi ngers by dipping a shaft-shaped object into the top of the reservoir opening. Re-
install the reservoir breather.
9.
Finally, raise the lift and disengage the maintenance bars by returning them to their stored position.

Changing the Hydraulic Oil (Every 12 Months)
1.
Change the hydraulic oil every 12 months of service or more often if conditions warrant. The frequency of fl uid change will depend upon
the general working conditions, severity of use and the overall cleanliness and care given to the lift. To do so, raise the unloaded platform
to its maximum height and engage the maintenance bars. Lower the lift onto the maintenance bars. Depress and hold the DOWN button
or pedal for several seconds to allow any residual hydraulic pressure to diminish.
2.
For models L2K and L3K remove the snap ring that secures the upper cylinder pin and then remove the upper cylinder pin. The L5K uses
roll pins to secure the upper cylinder pins. Using a small punch drive the roll pins out and then remove the upper cylinder pins.
3. The
hydraulic
fl uid inside the cylinder needs to be purged from the system. Disconnect the hydraulic line from the power unit and place
