INSPECTION
IMMEDIATELY upon receipt of the lift table, remove all packing and strapping material and visually inspect the unit for damage. Any damage
to the unit MUST BE NOTED on the delivery receipt. After the preliminary inspection is conducted, the unit should be thoroughly inspected for
any concealed damage that was not readily apparent during the preliminary inspection. Any concealed damage found that was not noted on the
delivery receipt should be IMMEDIATELY reported in writing TO THE DELIVERING CARRIER.
SAFETY DEFINITIONS
Bishamon uses the following system to identify the degree of risk associated with hazards and unsafe practices.
DANGER - Immediate hazard which will result in SEVERE PERSONAL INJURY or DEATH.
WARNING - Hazard or unsafe practice which could result in SEVERE PERSONAL INJURY or DEATH and PROPERTY DAMAGE.
CAUTION - Hazard or unsafe practice which could result in MINOR PERSONAL INJURY and PROPERTY DAMAGE.
DANGERS
1. READ THIS MANUAL COMPLETELY BEFORE USING AND THOROUGHLY UNDERSTAND AND FOLLOW ALL SAFETY
INSTRUCTIONS.
2. A falling lift table can cause SEVERE PERSONAL INJURY or DEATH. NEVER go under the platform until the load is removed and the
scissor mechanism is secured in the raised position with the maintenance bars.
3. The maintenance bars have been designed for use only when the lift is UNLOADED. NEVER place any load on the platform with the
maintenance bars engaged. SEVERE PERSONAL INJURY or DEATH and PROPERTY DAMAGE could result.
4. NEVER sit, stand or ride on the platform. Moving components could cause loss of balance. SEVERE PERSONAL INJURY or DEATH
could result.
5. The lifts electrical circuits use voltages, which can cause SEVERE PERSONAL INJURY or DEATH. DO NOT work with the electrical
components unless you are a QUALIFIED ELECTRICAN
6. The lift’s electrical components can create sparks. DO NOT install the lift in an area where potentially explosive dusts, gases, or vapors
may be present. Failure to comply may result in an explosion and cause SEVERE PERSONAL INJURY or DEATH.
WARNINGS
1. The OPTIMUS lift table is designed for use with stable, uniformly distributed loads on a solid level fl oor. DO NOT concentrate the load at
one point on the platform or pallet. ALWAYS uniformly distribute each layer of load over the supporting surface. DO NOT use the lift for
any purpose other than its intended use.
2. DO NOT install the lift table on an unlevel or soft surface. The lift base frame must be supported along its entire length and width. Failure
to completely support the base frame could result in damage to the lift.
3. DO NOT use the lift table with an unstable, unbalanced or loosely stacked load. Unbalanced loads may become unstable and fall.
SEVERE PERSONAL INJURY and PROPERTY DAMAGE could result.
4. DO NOT overload the lift table. ALWAYS stay within the designated capacity ratings. SEVERE PERSONAL INJURY and PROPERTY
DAMAGE could result.
5. SHEARING HAZARD. ALWAYS keep hands and feet clear of the scissor mechanism and all moving components. DO NOT put hands or
fi ngers under the platform when in use. SEVERE PERSONAL INJURY could result.
6. CRUSHING HAZARD. ALWAYS keep hands and feet clear of all moving components. DO NOT put feet on the base frame when in use.
SEVERE PERSONAL INJURY could result.
7. PINCH POINT HAZARD. ALWAYS keep feet, hands and fi ngers away from the underside of the platform and all moving components.
SEVERE PERSONAL INJURY could result.
8. DO NOT change the relief valve setting. The relief valve is installed to protect the operator and the lift table. Changing the relief valve
setting may compromise the performance and safety of the lift. SEVERE PERSONAL INJURY and PROPERTY DAMAGE could result.
9. NEVER leave the loaded lift table unattended unless the platform is in the fully-lowered position.
10. ALL lift servicing must be performed by qualifi ed personnel only. Unauthorized modifi cations to this lift table, its hydraulic power unit or its
control system may compromise the performance and safety of the system. UNDER NO CIRCUMSTANCES should you attempt any repair
or service that is not covered in this manual.
11. The release of fl uids under high pressure can cause SEVERE PERSONAL INJURY. Before servicing the lift, ALWAYS remove all load,
engage the maintenance bars and RELEASE THE HYDRAULIC PRESSURE.
1
12. ALWAYS ensure all safety warning labels are in place and legible. If not, remove the lift table from service and replace the required labels.
Refer to Figure 1 for label descriptions and locations.
13. ALWAYS securely anchor the base frame to the fl oor to ensure maximum stability.
CAUTIONS
1. DO NOT continue to operate the pump if a squealing noise is heard coming from the pump. The pressure relief valve is operating.
Continued use of the pump with the relief valve operating may cause permanent damage the pump. REDUCE the load to prevent the relief
