table 1: Single Battery Lifting Distances in either direction for DeWalt 18V Drill (Model DCD990M2)
100kg Load
141kg Load
* Lifting distance based on full battery charge, ambient temperature of 22° C.
** High speeds with high loads not recommended.
note: Power Drill lifting capabilities will vary with victim load, battery charge, drill model, and
environmental conditions. The lowest drill speed setting is recommended to maximize battery life and to
reduce the risk of damaging the drill or the R550 Descender. Loads greater than 141 kg should not be lifted
with the Power Drill option. Lifting in reverse direction will typically decrease the lifting distance capacity of
a single battery charge.
step 4. Prepare the Lifeline for Descent: Prior to descent, the section of lifeline between the user and
the R550 Descender must be tightened to remove any slack. Tighten the lifeline by pulling on the
free end of the lifeline until slack between the user and R550 Descender is removed. Once the
lifeline is taut, hold the free end of the lifeline tightly until descent is initiated.
step 5. Descend to safety: Release the free end of the lifeline to initiate descent. Descent speed will be
automatically controlled to a rate described in Section 1.2 C by the R550 Descender's centrifugal
brake. Descent may be interrupted by firmly grasping the free end of the lifeline (see Figure 6).
Bend your knees to prepare for landing. After landing, disconnect the lifeline from the body
support. Record all descents in the Descent Log (Section 9).
cautIon:
parts other than those used to control the descent are touched. Use beyond the specified load and descent
length limits may generate excessive heat which could damage the descent line.

assistance, simultaneous rescue/escape allows a rescuer
WarnInG:
combined weight (including tools, clothing, body support, etc.) of 282 kg and a descent distance of 200 m.
step 1. Descend to the victim: In situations where the fall victim is suspended by their existing fall
arrest subsystem, it will be necessary for the rescuer to descend to the victim's location to provide
assistance. Descend to the victim per the steps in Section 3.4.
IMportant:
holding the free end of the rope. (See Figure 6) If a secondary rescuer is available at the R550 Descender,
the free end of the rope can be passed through the pigtail and then secured in the cam cleats to prevent
unintentional descent while the primary rescuer is securing the victim.
step 2. connect the victim to the R550 Rescue & escape Device: Connect a rescue lanyard (RL)
(or similar equipment) between the lifeline snap hook connected to the rescuer's full body harness
front D-ring (RD) or the back D-ring on the victim's full body harness (C).
WarnInG:
which may result in serious injury.
step 3. Disconnect the victim's Fall Arrest subsystem: Ensure that the victim is securely attached
to the R550 Rescue & Escape Device and then detach the victim's fall arrest subsystem (lanyard,
etc.) to free the victim for descent.
note:
victim slightly for detachment of their fall arrest subsystem.
step 4. Descend to safety: Release the free end of the lifeline to initiate descent. Descent speed will be
automatically controlled to a rate described in Section 1.2 C by the R550 Descender's centrifugal
brake. Descent may be interrupted by firmly grasping the free end of the lifeline (see Figure 6).
Bend your knees to prepare for landing. After landing, disconnect the lifeline from the body support.
Record all descents in the Descent Log (Section 9).
cautIon:
parts other than those used to control the descent are touched. Use beyond the specified load and descent
length limits may generate excessive heat which could damage the descent line.
1 rescuer: Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.
