Electric lifting/pulling winch
2.3.1
Working cycle
The PCT1800 AC Electric Portable Capstan Pulling/Lifting Winch
is designed for intermittent use. The motor manufacturer
recommends duty cycle of 25%. So, to get a maximum lifetime out
of the engine, it should only be used for fifteen (15) minutes period
every hour. This data varies depending on the loads pulled or lifted.
Light loads can be lifted or pulled continuously without affecting the
life of the engine. Continuous pulls are however less damageable
for the motor than frequents stop and go.

Initial inspection and test
When the new or factory refurbished winch is first put in service,
perform the following:
2.4.1
Engine
(PCH1000 and PCH2000 only)
1)
Check oil level (see Honda Owner's Manual);
2)
Check air filter (see Honda Owner's Manual);
3)
Check fuel level (see Honda Owner's Manual);
4)
Test On/Off switch by starting the engine with switch on,
and turning it off. If the engine fails to turn off, it can be
shut down by closing the choke.
5)
Test emergency STOP switch by starting the engine with
switch on, and pressing the emergency switch after to
turn the engine off. If the engine fails to turn off, it can be
shut down by using the on/off switch. (PCH2000 only).

Winch operation
2.4.2.1 Test throttle adjustment
Without rope on the drum:
1)
Pull on plate and confirm that the maximum course is
reached (Figure 1, A);
2)
Observe drum rotating under full throttle;
3)
Release plate and confirm the minimum course is
reached by spring return action (Figure 1, B);
4)
Observe drum not rotating when engine is idling;
5)
If there are any adjustments to be made, perform the
adjustments and re-test.
6)
Listen for any unusual noise.

2.4.2.2 Test rope grabbing system
1)
With the rope grabbing system (brake) engaged: Attach
winch to suitable anchor and attach rope to fixed point at
some distance directly in front of the winch (see below figure);
2)
Pull rope until rope is under tension and let go of the rope;
3)
Observe that the tension is maintained by
(PCT1800 only)
The winch must be plugged into a
grounded plug. The use of an
extension cord can cause a loss
of power at full capacity. As listed
on the product label (figure 1),
make sure the voltage and
current type are respected. Units
115V-60hz require 20 amps while
the units 220V-50hz require 10
amps circuit breaker.

the rope grabbing system.
4)
To release this tension, follow steps 1 to 7 in
section 3.6.2 Lower a load.
TM
2.4.2.3 Test winch anchoring
1) With the rope grabbing system (brake) disengaged (see
section 3.6.2.3): Test anchor by exerting twice the maximum
pulling force of the winch, using a block attached to a fixed point
and attaching the rope end to the anchor point (see adjacent
figure)
2) If the anchor is moving or show any sign of potentially moving,
find a new anchor point and perform the test again.
3) IMPORTANT: Document this initial inspection as the first
Periodic Inspection in the log at the end of this document.

DO NOT ANCHOR THE ROPE BACK TO THE WINCH.
MOST WINCHING SITUATIONS PRESENT POTENTIAL
DANGERS!
WHEN THE ROPE IS UNDER TENTION, MAKE SURE THAT
NO ONE IS WITHIN 2.5 METRES OF THIS AREA (fig.1)
