4. Description and use of operator's controls. Two controls (crank and brake units) are used
in the operation of reel unit RL-31-E. All other models (single axles) use only one brake and
crank.
a. Crank GC-4-A is used to manually turn the axle of all models when wire is being
recovered. (See Figure 22.) Use the hole nearer the end of the crank if you have heavy wire
to pull in. Use the other hole if you have lighter wire to pull in and you want to reel it in faster.
(See Figure 23.)

WARNING
It is important to keep your face away from the crank. The
crank may slip off and injure you.
b. Brake unit. The purpose of the brake unit is to provide the operator with sensitive
control of reel rotation during pay out of wire. This control is necessary to prevent the reel from
paying out wire faster than is needed. The braking effect is produced by adjusting the
pressure between stationary steel disks and composition disks that revolve with the axle.
WARNING
Always wear gloves when paying out or recovering field wire.
