12. Disengage the maintenance safety bars and lower the lift to check for proper height. The plat-
form should be flush with the curb angles around the pit.
13. Operate the lift through a few cycles holding the ''DOWN'' button on for 10-20 seconds after
the lift is fully lowered. This procedure will bleed any remaining air that may be in the hydraulic
lines.
14. For lifts equipped with an upper travel limit switch, raise the lift again and set the limit switch
(normally closed contact) so that the motor shuts off when the platform reaches the desired height
from the ground.
15. Note to Installer: In order to ensure a clean, trouble free, hydraulic system and to prevent the
suction filter from clogging due to foreign particles in the pipe, the installer must run the lift ''UP''
and "DOWN'' at least 15 times. Lower the lift and turn off the power supply. Remove the solenoid
valve from the valve block and clean thoroughly, making sure that the dirt does not enter the
valves. This procedure will ensure trouble free operation of the lift.
16. Check the oil level of the reservoir with the lift fully lowered. It should be approximately 1''
below the top of the tank. Add oil if necessary.
17. Clean up spilled oil and debris from the area.
Note to installer; Spilled oil left in the area may be misinterpreted as a leak and may cause a
needless "call- back''.
The SizzrDok series of lifts have been primarily designed for loading dock applications. The most
important advantage of the SizzrDok is that it is finitely adjustable in height. The installation of this
lift provides full flexibility, allowing you to load and unload at any truck bed elevation within the
lift's travel range. The general specifications for the SizzrDok Series Dock Lifts are as shown in
Figure 3.
To Engage the Maintenance Bars; HLD:
1. REMOVE ALL LOADS from the platform and depress the "up" button to raise the dock lift
to its fully raised position.
2. Rotate each maintenance bar until it hits the inside of the roller channel. Ensure both
maintenance bars are properly positioned against the roller channel.
3. Lower the dock lift by pressing the "DOWN" button until the rollers stop against the
maintenance bars and the lift ceases to come down any further.
