4. After completing the trial run, return the carriage assembly to the base
position and load the hoisting carriage with material. Material should be
placed flat and evenly at the center of the carriage platform.
CAUTION: DO NOT EXCEED THE HOIST WEIGHT LIMIT. REFER TO CHART
IN SAFE OPERATING PROCEDURE Section II, Paragraph B.4. TO
DETERMINE MAXIMUM CAPACITY FOR YOUR HOIST.
5. Manually increase engine speed to full throttle
.

.
With engine at full throttle, apply foot pressure on treadle. This will
engage winch and start carriage in its upward travel. Foot pressure
on the motor base assembly treadle must be maintained throughout
the upward travel of the carriage assembly. THE FIRST TIME YOU
USE THE HOIST EACH DAY, STOP THE LOADED CARRIAGE AFTER IT
MOVES TWO FEET TO MAKE SURE THE BRAKE IS WORKING PROPERLY.
7. Once carriage starts its upward travel do not stop its motion until it
reaches the Peak. Upon load reaching peak, release foot pressure
and the load will be able to be unloaded down the carriage flap.
Always release foot pressure when Hoist reaches top and before unloading.
NOTE: Should carriage stop in mid-climb, brake will hold load. Do Not
Return loaded carriage to ground. Hoist is not designed to lower a loaded
carriage. If necessary restart engine and/or reapply foot pressure on treadle
and complete hoisting. Only if engine CAN NOT be restarted, use Brake
Release Handle to lower carriage VERY SLOWLY.
8. Once load is unloaded on to roof:
a. Brake is always on. Therefore, by lifting up on Brake Release Handle,
brake will release. Carriage will then lower.
b. CAUTION-Upon releasing brake, carriage will free fall. Allow the
carriage to lower about 12 inches at a time as it descends by pushing
on the Brake Release Handle slowly at steady intervals. LET GO OF
THE HANDLE to stop the carriage.
IMPORTANT: IF CARRIAGE DOES NOT MOVE DOWN AFTER LOAD IS REMOVED AND THE BRAKE
RELEASE HANDLE IS LIFTED, IT MAY BE CAUSED BY A NEW BRAKE BAND OR THE FIRST FEW
USES OF A NEW HOIST. TO WEAR IN NEW BRAKE BAND RAISE LOAD TO ROOF. REMOVE LOAD
BUT LEAVE 40-50 POUNDS OF LOAD ON CARRIAGE AND USE BRAKE RELEASE HANDLE TO
LOWER CARRIAGE. EXAMPLE: RAISE 2 OR 3 BUNDLES OF SHINGLES TO ROOF. DEPEND ON
WEIGHT- DO NOT EXCEED WEIGHT LIMIT
OF HOIST. LEAVE 1 BUNDLE OF SHINGLES ON
CARRIAGE AND LOWER CARRIAGE SLOWLY. DO THIS UNTIL FOR A DAY OR TWO UNTIL YOU
CAN RAISE AND LOWER CARRIAGE WITH NO WEIGHT ON IT.
