Adjusting the Brakes
The brakes are adjusted at the factory, but should still be checked before every use. If the braking
power is insufficient, the brakes should be adjusted. Perform the adjustment on a dry, non-slippery
surface.
There are two forms of adjustment. One adjusts the brake cable tension and the other adjusts the
set of brake calipers. Adjusting the brake cable tension is usually sufficient. If you are unable to
achieve sufficient braking force by tightening the cable or if one wheel brakes more effectively than
the other, you may need to adjust the brake caliper.
Adjusting the Brake Cable Tension
1. Loosen the screw (1) that locks the brake cable mount using a 3/16” Allen wrench.
2. Adjust the tension in the cables by turning the brake adjustment screw (2) that protrudes from
the bottom of the brake cable mount using a 3/16” Allen wrench.
3. After adjusting the brake adjustment screw, re-tighten the locking screw.
4. To test the tension, squeeze the brake lever tightly, tilt the unit back about 35°, and push the unit
forward along the ground. The combined action should make the wheels skid on the ground.
5. If the wheels spin, the brakes are not adjusted correctly. If the cable is too tight, it may engage
the brakes when you are not pulling on the brake lever.
Adjusting the Brake Calipers
The brake calipers can be adjusted using a 3/16” hex screwdriver. The brake caliper screws are
accessed between the wheel spokes on either side.
1. Adjust the brake cable mount to its highest position as described in the preceding section
(Adjusting the Brake Cable Tension).
2. Turn the brake caliper screw clockwise as far as it will go without excessive force.
3. Back both screws off one half turn in the opposite direction.
4. To test the caliper adjustment, push the unit around while not engaging the brakes. If you
feel that either brake is dragging too much, try backing out the screw another 1/8 of a turn
at a time until the unit rolls freely. Note: It is normal for the brakes to rub slightly, but they
should not drag enough to interfere with easy rolling of the unit.
5. Perform the full brake cable tension adjustment as described in the previous section.

Lubrication Points
Advanced Troubleshooting Guide
How do I know if the battery needs to be replaced?
Indications that it might need replacement:
• Does not hold a charge
• Slower lift speed
• Grinding noise
• Unit won’t lift at all
• Shorter time in between charging
• Battery is leaking
Diagnostic Instructions:
1. Check the charger with a multi-meter set to Volts DC. Place the positive lead in the center of the
adapter and touch the negative lead to the outside (Figure 1). Voltage should read 15V or higher
when plugged into an AC outlet.
2. Remove the battery cover and remove wires from the terminals; measure the voltage across the
wires when the charger is plugged into the LiftPlus and the AC outlet (Figure 2). Should read
approximately 15V. This means power is getting from the control board to the wire terminals.
NOTE: This voltage may have slightly lower readings because the controller will limit charge
getting to battery in relation to how much “charge” is in the battery - the higher the battery
charge, the lower the voltage going in. This permits you to leave the charger plugged into the
LiftPlus as often as you’d like without overcharging it.
3. With the terminal wires still removed from the battery, measure the voltage across the battery
terminals (Figure 3). Ideally the battery should read 12 to 12.6V.
4. If the voltage is lower than 12V:
• Charge overnight.
• After charging, check voltage across battery terminals:
• Under 12V - replace battery
• 12 to 12.6V - Normal
• Place a load on the LiftPlus and run up and down a few cycles. If voltage drops from 12V, you
should replace the battery.
Figure 1
Figure 2
Figure 3
How do I test switch functionality?
Please use caution when removing covers and exposing moving parts.
Diagnostic Instructions:
1.
Remove battery cover and remove the wires from the battery terminals. Hook Multi-Meter
to wire terminals and set range to Kilo-Ohms.
2.
Check Power Switch
• OFF
• Make sure power switch is turned OFF.
• Record the reading. Example in picture is 84.7 K-Ohms.
• ON
• Good: Turn power switch on and if the power switch and breaker are functioning
properly then the meter will read a lower resistance. Example in picture is 1.158
K-Ohms.
• Bad: If the power switch or overload circuit is bad, then the reading will not change.
• Check the overload circuit for continuity:
• Place the black power lead on the LH circuit terminal and the red power lead on the
RH terminal. A functioning overload circuit will show 0 K-Ohms.
• If the overload circuit is good, then replace the power switch.
3.
Check Up/Down Switch
• Make sure power switch is turned ON.
• Up
• Good: Press the Up/Down switch to Up and the meter will read a lower resistance.
Example in picture is .1253 K-Ohmns (or 125.3 Ohms).
• Bad: If no change in meter, check the wire connections. If the wires are properly
connected, then replace the Up/Down switch.
• Down
• Press the Up/Down switch to Down and the meter will read a lower resistance.
Example in picture is .2449 K-Ohmns (or 244.9 Ohms).
• Bad: If no change in meter, check the wire connections. If the wires are properly
connected, then replace the Up/Down switch.
4.
Check Control Board
• If the switches are operating correctly, then determine whether the terminals on top of the
control board are getting power to the motor.
• Remove the top covers from the LiftPlus. Remove the Multi-Meter from the battery and
reconnect the battery. Change the range on the Multi-Meter to volts.
• Connect the Multi-Meter to the motor terminals on the control board.
Readings should be:
• 0 volts when switch is OFF
• 12 volts when switch is ON and Up/Down switch is pressed Up or Down.
• If there is no voltage on the motor terminals when there should be,
contact Magline.
Motor Terminals
The motor works in only one direction.
Please use caution when removing covers and exposing moving parts.
Please try these steps first:
• Check for dirt and other obstructions
• Lubricate the lift screw; see pages 13-14 for instructions.
Diagnostic Instructions:
1.
Remove the motor cover from the LiftPlus. Check the wire connections to the upper and lower switches
and the board. Fix any loose connections; replace any damaged wiring.
• If it will lift, but not lower - check upper limit switch (see Step 2); replace if needed
• If it will lower, but not lift:
• Check overload circuit - reset if needed
• Check lower limit switch (see Step 2); replace if needed
2.
Check switch continuity - set multimeter to Continuity Test mode
• Upper limit switch
• Unplug the wire from the NC terminal on the switch (see diagram below)
• Place the black power lead on the common terminal; place the read power lead on the NC terminal
on the side of the switch. A properly working switch will show continuity when the red lead is on the
NC terminal AND the switch is not depressed. It will show incomplete circuit (open circuit) when the
read lead is touched to the NO terminal on the side of the switch AND the switch is not depressed.
• Replace if the switch is damaged.
• Lower limit switch
• Unplug the wire from the NC terminal on the switch (see diagram below)
• Place the black power lead on the common terminal; place the read power lead on the NC terminal
on the side of the switch. A properly working switch will show continuity when the red lead is on the
NC terminal AND the switch is not depressed. It will show incomplete circuit (open circuit) when the
read lead is touched to the NO terminal on the side of the switch AND the switch is not depressed.
• Replace if the switch is damaged.
• Up/Down switch (see page 16)
3.
If the switches are operating correctly, then determine whether the terminals on top of the control board
