Empulse R90: Let's Go! Guide

Driving

Let's Drive!

Start slow. Sunrise Medical recommends using anti-tips while operating the R90. Before you start, ensure the Control Box is connected.

+ Press once to lower the wheel. You will hear an audible signal from the R90 when the wheel is completely lowered.

Press to start the R90 and increase speed. Press the button in 0.5-second increments to continue increasing your speed. You cannot hold the button or press it faster to speed up.

Pro Tip: You can manually propel the chair to your desired speed and then press the plus button once to maintain that speed.

Press to slow down.

Press to stop power to the R90.

Maneuvering

The R90's position directly under the chair allows you to maneuver and turn within your chair's original footprint.

Use the R90 to accelerate to a comfortable speed. Practice turning by applying pressure to one hand rim or the other, in both directions and at different speeds.

Pro Tip: The R90 senses tight turns and decreases speed accordingly. The indoor drive profile is more sensitive to this than the outdoor drive profile.

Hills and Ramps

Start slow. Sunrise Medical recommends using anti-tips while operating the R90. Find a straight and moderate incline to practice.

Going Up

Starting at least 3 meters from the base of the incline, start the R90 and gain momentum as you approach. As you ascend, the R90 automatically increases motor power to help propel you up the incline. Shifting your torso forward can improve riding sensation and stability.

Going Down

If going down a slope, the R90 stops power to the motor. The R90 does not have a braking mechanism; you must perform all braking and speed control.

Pro Tip: When you reach the bottom of the incline, coast to your desired speed and press the Plus Button once to maintain it.

Warning

Using a power assist device can alter your center-of-gravity or how your chair rides. To reduce the risk of tip-over or falls, consult your healthcare provider about proper wheelchair configuration, including the use of anti-tips and any other necessary adjustments.

Install & Set-Up

Attach the Receiver Clamp

Loosely fit the receiver clamp to the axle tube. It should be snug but still able to be manipulated or rotated on the tube.

Pro Tip: Flip the chair over to more easily access the axle tube.

Note for Folding Chairs: Refer to your owner's manual for instructions on installing the removable axle tube. Depending on your camber tube size, a spacer may be included for optimal clamp fit.

Center the Receiver Clamp

Use a tape measure to find the middle of the axle tube. Position the receiver clamp so there is equal distance between the clamp and each wheel.

Pro Tip: On QUICKIE® rigid chairs, align the center hole of the axle tube with the center hole of the R90 receiver clamp. Threading a small Allen wrench through these holes will easily align them.

Level the Receiver Clamp

While seated, have someone adjust the receiver clamp to be level. Tighten all 6 screws to 5.8 ft-lbs (7.8 Nm) to secure the receiver clamp.

Torque Specification: 5.8 ft-lbs (7.8 Nm)

Set the Wheel Up Position

With the wheel in the up position, slide the R90 into the receiver clamp. The V-lock™ system will secure the R90.

Slide the included wheel height gauge under the wheel. The wheel height should be no higher than the thick side ("NO GO", 3/8" or 9.5mm) and no lower than the thin side ("GO", 1/4" or 6.4mm).

Adjust the Wheel Height

Slightly loosen the two actuator fasteners (A) on the back of the R90 using a 4mm Allen wrench. Adjust the wheel height using the manual height adjustment screw (B). Position the wheel between the "GO" and "NO GO" heights on the gauge. Retighten the actuator bolts to 8.85 ft-lbs (12 Nm).

Torque Specification: 8.85 ft-lbs (12 Nm)

Pro Tip: Insert the Allen wrench into the manual height adjustment first, then attach the R90 to the chair.

Note: If the Allen wrench interferes with attaching the R90, do not force the connection, as this may damage the height adjustment.

Check: While seated, have someone use the power button to raise and lower the wheel. The wheel should touch the ground in the lowest position and have 1/4 to 3/8 inch (6.4-9.5mm) of ground clearance when raised.
