Adjust the lift's speed using the vertical switch and maneuver with precision using the joystick. Prioritize safety by donning a secure safety harness and waiting for the lift to come to a complete halt before making any adjustments. It's worth noting that different brands may vary slightly in controls and sensitivity, necessitating familiarization before operation.
Key Steps
Activating and Deactivating the Machine
Entering the Scissor Lift Safely Accessing the scissor lift involves navigating through its protective gate. Unhook the chains or unlatch the gate to gain entry. Stepping onto the base, maneuver under the top rail to enter securely. Upon entry, ensure to lock the gate or reattach the chains for added safety.
- For gated entries, locate the locking mechanism at the frame's juncture and disengage it for access.
- Operating the scissor lift without securing the gate is strictly prohibited.
Igniting the Lift: Insert the key into the ignition slot to activate the scissor lift. Locate the ignition adjacent to the prominent red button on the control panel. Turn the key clockwise to power up the lift. The control panel, housing the joystick, is situated within the lift's cabin.
Pro Tip: Typically, operators and rental agencies leave the key in the ignition when the lift is not in use. If the key's whereabouts are unknown, start your search from the control panel.
Emergency Halt: Depress the large red button (commonly known as the Emergency Stop or 'E-Stop') to instantly halt the machine's operation. Should there be a need to disengage power or if control over the lift is compromised, press this button to cut off power supply immediately.
- To reactivate the lift post-emergency stop, pull out the button and utilize the key to restart the scissor lift.
Vertical Movement
Activating Hydraulics: Engage the hydraulic system by toggling the horizontal switch to the left position. Located on the control panel, this switch has two settings—left and right. Setting it to the left activates the hydraulic mechanism, enabling vertical movement of the scissor lift. Some models may have labeled switch positions; on such lifts, set the horizontal switch to 'Platform' or 'Up/Down' position.
Insider Tip: Reset the horizontal switch to its neutral position by shifting it to the middle. Activating the switch to the right powers the wheels. Always verify this switch before maneuvering the joystick.
Adjusting Speed: Utilize the vertical switch to set the lift's speed to “slow.” It's seldom necessary to opt for the “fast” mode, positioned upwards. Opt for the lowest setting to ensure gradual elevation and controlled movement. Some lifts label this setting as “slow.”
- Maintain caution to prevent accidents or loss of control, especially during rapid movements.
- The fast setting is typically used in warehouses for accessing higher shelves where driving isn't required.
Raising the Lift: Shift the joystick forward to elevate the scissor lift. With the switch on the left, push the joystick forward for upward movement. To halt elevation, center the stick or release it for automatic cessation.
- Joysticks in scissor lifts are designed to return to the center position upon release, halting movement.
- During ascent, maintain vigilance to avoid collisions and ensure safety of surroundings.
- Ensure no individuals are in close proximity to the lift during elevation.
Lowering the Lift: Pull the joystick backward to initiate descent. Continuous backward pull results in gradual lowering. Cease descent by centering the joystick or releasing it.
- Prior to descent, inspect the surroundings for safety, especially the folding rails which may pose a risk to nearby individuals.
- Keep watch below during descent to prevent accidents, avoiding descent if anyone is within 20 feet of the lift.
Operating the Scissor Lift
Prioritize Safety: Lower the scissor lift completely before initiating driving maneuvers. Driving with the platform raised increases the risk of tipping over. Never operate the lift with the platform elevated.
- Moving a raised scissor lift may constitute a safety violation depending on local regulations.
Engage Drive Mode: Position the horizontal switch fully to the right to deactivate hydraulic power and engage drive mode. Locate the horizontal switch on the control panel and shift it completely to the right. This position is typically labeled as “drive” if controls are marked.
- Platform adjustments are disabled in drive mode, so always lower the platform before activating this switch.
Maintain Safe Speed: Ensure safety by setting the vertical switch to the “slow” position while operating the lift. Adjust the switch to the lowest position to retain control during driving maneuvers.
- “Fast” mode is typically used for navigating warehouse aisles where lateral movement isn't required.
Controlled Driving: Drive the lift by manipulating the joystick forward or backward with the horizontal switch set to the rightmost position. Push forward for forward motion and pull backward for reverse. Always wait for the lift to stop completely before changing direction.
Enhanced Joystick Functionality: Modern scissor lift joysticks are designed to respond to varying degrees of pressure when in drive mode. Gentle movements result in gradual motion, while full deflection maximizes speed according to your setting.
Utilize the toggle atop the joystick for lateral movement. To alter directions, employ the toggle switch situated atop the joystick. Press the left side to veer left and the right side to veer right. Maintain pressure on the switch for continuous rotation as you drive.
- Scissor lifts lack sharp turning capability, often necessitating multiple inputs for tight corners.
Exercise Caution and Take Breaks for Safety. Maneuvering a scissor lift can be challenging, particularly for inexperienced operators. Prioritize safety by using one control input at a time, monitoring speed and direction meticulously. Release the joystick between inputs to ensure a complete stop before changing direction. Never alter direction without allowing the lift to halt entirely.
- While driving, maintain focus on the ground for obstacles or surface changes. Outdoors, periodically scan upward to avoid potential hazards like power lines or trees.
- Refrain from rapid back-and-forth joystick movements during direction changes to prevent instability or falling hazards. Quick movements may also result in collisions or platform disruptions.
Ensuring Safety Measures
Secure a safety harness and tether it to the platform strap. Acquire a safety harness from construction suppliers or lift manufacturers. Wear and fasten the harness centrally and on the sides for security. Tighten the straps to fit snugly. Attach the hook end of the retractable nylon strap, found on the platform floor, to the harness for fall protection.
- The nylon strap extends up to 6 feet before locking, providing ample maneuverability on the platform.
Monitor Battery or Fuel Levels to Prevent Stranding. Check the gauge adjacent to the control panel switches for fuel or electricity status. Vigilantly monitor these levels to avoid depletion while elevated.
- Running out of energy while elevated requires assistance to recharge or refuel before descent. (Alternatively, consult the manual or manufacturer for the manual pressure relief valve, allowing descent regardless of energy status.)
- Most scissor lifts operate on electric power.
Choose Stable Ground: Operate the scissor lift solely on stable, level surfaces. Avoid grass, gravel, or uneven terrain, as these can compromise stability and pose significant safety risks. Utilize asphalt, concrete, or hardwood surfaces for safe operation.
Important Reminder: Operating a scissor lift on uneven surfaces is often prohibited by law.
Prioritize Inspection: Thoroughly inspect the scissor lift before usage for signs of wear and tear. Conduct a visual examination around the machine, checking wheels for damage, tires for proper inflation, and platform rails for cracks or blockages to ensure safe operation.
- If uncertain about the lift's safety, seek inspection by a certified mechanic before use.
Obtain Operator Certification for Enhanced Safety. Employers are legally obligated to provide scissor lift training for operators. Consider attending a safety course to obtain operator certification, even if not mandatory. Certification minimizes the risk of critical errors during operation.
- Scissor lift operator certifications typically require less than a week to complete.
- In some regions, mandatory training is enforced for scissor lift operation, although optional elsewhere.
- While requirements vary, scissor lifts are often categorized as scaffolding, which may not necessitate certification for use.
Useful Advice
-
For tasks involving material handling or hydraulic testing, utilize the secondary control panel located at the lift's base. This panel is typically secured behind a cover on one of the longer sides of the machine.
-
Many scissor lifts offer the option to extend the platform for increased maneuverability. Look for the pin locking mechanism securing the frame, and extend it horizontally at ground level. Keep in mind that extending the platform reduces the lift's weight capacity and increases susceptibility to sway when raised. Refer to the lift's safety sticker for weight limit information.
Cautionary Notes
- Avoid exerting excessive force while handling objects in elevated positions on a scissor lift, as even minimal force can cause tipping, especially at height.
- Annual inspection by a certified mechanic is imperative for scissor lift maintenance. When renting, request inspection records to ensure proper functioning before making any payments.
- Avoid operating a scissor lift in windy conditions, as even moderate winds can topple a raised lift. Exercise caution and refrain from raising the lift in windy conditions.
- Adhere to weight restrictions and avoid overloading the platform with heavy materials. Refer to online resources or the safety sticker on the control panel for weight limit information.
