5 OPERATING PROCEDURE
IT IS IMPERATIVE THAT ALL PERSONS USING, OPERATING OR
MAINTAINING THIS DRUM TRAILER BE FULLY TRAINED AND
COMPETENT TO DO SO, AND HAVE READ THE ENTIRE
OPERATING MANUAL.
CBS PRODUCTS LTD CANNOT BE HELD RESPONSIBLE FOR MIS-
USE OF THIS EQUIPMENT.
5.1 ATTACHING TO VEHICLE
The CBS 823-13 Cable Drum Trailer has been designed for towing behind a category
M1, M2 or N1 vehicle, therefore ensure that the towing vehicle has the correct towing
arrangement to match the trailer. It should also be at a height that enables the trailer
to travel in a horizontal position, and not leaning up or down, (Ensure that there is a
positive nose weight), if the latter is the case, the vehicle towing arrangement should
be adjusted to suit.
The towing facility on the trailer is to E.U. specification and is of the inertia type (i.e.
overrun). The towing bracket is fitted with a handbrake for holding the trailer in the
stationary condition. It is essential to apply the handbrake when the trailer is
separated from the towing vehicle.
The adjustable height jockey wheel allows the towing eye to be adjusted to
ease the operation of attaching the trailer to the vehicle. Once attached the
safety wire should be applied around the towing pin of the vehicle.
The 13 pin lighting plug is wired to current E.U. regulations. The plug should be
connected to the vehicle socket before towing commences.
To avoid problems with the electrics it is advisable to ensure the plug is kept dry and
free from dirt. When fitting and removing the plug do not pull on the connecting
cables.
5.2 LOADING THE TRAILER
It is safer to load and unload the trailer when it is attached to the vehicle, and to
adhere to the following:

5.4 WINCH OPERATING INSTRUCTIONS
See Winch manual, section 12, for operating instructions and general
winch safety information.
5.5 POSITIONING AND BRAKING OF CONDUCTOR DRUM
Once on site, position the trailer at approximately 20-30 metres distance from the first
pole to be strung. Align the trailer so the centre of the drum is in line with the first
pole. This ensures the conductor comes off the drum without fouling the drum
flanges.

15
Ensure the drum is loaded with the conductor feeding off the top of the drum.
Anchor the trailer down, by either leaving attached to towing vehicle or by
the use of slings and ground anchors (CBS 804), and also apply the
trailer brakes. Lower the rear prop stands of the trailer to stabilise during
the pulling operation, on soft ground it may be necessary to place wooden battens
under the rear prop stands to spread the load, the trailer must be stable and
adequately restrained.
Check that the drum retaining pins and brake pins are located correctly and have not
moved during transportation.
Do not use a drum that does not fit the drum collars.
If drums with larger diameter spindle holes are to be used, it is recommended that
you order special collars from CBS Products LTD. to suit in advance of operating the
drum trailer.
Band Brake:
For a drum braking operation apply the drum brake lightly by turning the tommy bar
on the screw handle. Rotate the drum slightly by hand to ensure that the brake band
is just making contact with brake drum.
Note: The tommy bar screw controls the braking at a coarse level, and should be left
set once the required tension is achieved. The brake lever provides finer control of
the tension and can be adjusted by the operator during the stringing operation if
necessary.
Disc Brake:
For a disc braking operation apply the disc brake lightly by taking out the R clip from
the castle nut on the disc brake and turning the castle nut. Always replace R clip after
adjustment of the brake. Rotate the drum slightly by hand to ensure that the brake
pads are just making contact with the brake disc. The brake lever can then be used
to provide more braking force as required.
Note: The castle nut controls the braking at a coarse level, and should be left set
once the required tension is achieved. The brake lever provides finer control of the
tension and can be adjusted by the operator during the stringing operation if
necessary.

6 MAINTENANCE AND SERVICING
6.1 WINCH
See winch manual for maintenance and servicing requirements.
6.2 AXLE BRAKES AND TYRES
The brakes fitted are the auto reverse type to make towing easier. The
maintenance of the drum brakes should be undertaken by trained personnel only,
and adjusted when necessary to ensure the drums just run clear when the wheel is
rotated in a forward direction only. It is important to keep these adjusted every 6
months, as too large a drum movement can affect the performance of the auto
reverse facility and parking brake.
After adjusting the drum brakes, remove any slack in the operating system by
loosening the lock nut and tightening the pull rod, but without pre loading brakes
(check this again by rotating each wheel in a forward direction).
The tyres should be kept at the correct pressure (refer to section 4 for details) and
checked weekly, the tyres should be checked daily for damage prior to use of the
trailer.
The linkage mechanism should be oiled weekly to ensure smooth operation and to
protect from moisture.
Check the condition of the brake cables weekly, replace if frayed or damaged.
Apply alight oil as required to ensure cables move freely.
6.3 SERVICING
Tow-eye and Axle:
a) Apply grease to ball and to cup of ball head after cleaning each item.
(Alternatively towing eye and jaw if fitted). This to be carried out each time the
trailer is to be towed.
b) Oil all moving parts weekly having wiped away all corrosion and dirt deposits.
c) Every 3,000 miles or 3 months, or as necessary, apply grease gun to grease
nipples fitted to the coupling using general purpose grease.
d) After first 500 miles, then every 3,000 miles (or more often if required), adjust
wheel brakes at back plate adjusting points, to take up any wear. Follow brake
manufacturers appropriate instructions in this respect.
NOTE: do not adjust for brake wear anywhere other than at the wheel brakes
themselves. An indication of break wear will be given by increased handbrake travel.

17
e) After adjusting the drum brakes, remove any slack in the operating system by
loosening the lock nut and tightening the pull rod, but without pre-loading brakes
(check this again by rotating each wheel in a forward direction).
f) Check the condition of the brake cables every week, replace if frayed or
damaged.
g) Check the condition of the brake away cable each time the drum trailer is used,
replace if kinked or damaged.
h) Check the condition of all pin retaining wires, each time the drum trailer is used,
replace if kinked or damaged.
i) Check the condition and function of all retaining ‘R’ clips each time the drum
trailer is used, (replace if worn, distorted or faulty).
j) Check the ball head for wear each time trailer is used, (if applicable).
Brake Band (if fitted):
a) Check wear of brake band lining, if worn to within 2 mm of the rivets the brake
band should be replaced.
b) Adjust tommy bar on the screw handle to accommodate wear as required.
c) Check brake drum for damage and replace as required.
d) Check for smooth operation of brake.
Disc Brake (if fitted):
a) Grease disc brake caliper mounting lugs and ensure free lateral movement of
caliper.
b) Check brake pad wear and replace as required.
c) Tighten castle nut on disc caliper to adjust for wear as required.
d) Check disc for damage, excessive corrosion and wear, replace as required.
e) Check for smooth operation.

18
7 TOWING INSTRUCTION
7.1 BEFORE TOWING
a) Check the ball head cup is well greased (if fitted).
b) Handbrake is fully applied.
c) Raise the coupling head above height of ball bracket by use of jockey wheel
provided.
d) Reverse towing vehicle until ball bracket is directly below ball head on coupling.
e) Grasp locking handle on top of coupling and press trigger backwards with thumb.
Then lift handle (you can now release trigger). With handle still raised wind up
jockey wheel until ball on towing vehicle enters ball cup on coupling. Now release
handle and continue winding up jockey wheel until locking handle automatically
drops down and trigger snaps shut. If this does not occur lift handle again and
check if ball seats this time and trigger snaps shut. If there is still no success,
check if ball or head is worn.
f) If ball seats properly, then continue winding up jockey wheel until it is fully
retracted.
g) If towing eye is fitted instead of ball head, remove pin from towing jaw and reverse
towing vehicle until eye enters jaw. Then replace pin and locking pigtail or other
securing device.
h) Continue to wind up jockey wheel until fully retracted and wheel is no longer free
to rotate. Loosen jockey clamp and raise jockey wheel up into chassis with wheel
facing rearwards and re-tighten clamp firmly ensuring wheel is well clear of brake
linkage, ensure that the rear prop stands are raised and that the retaining clip on
both rear prop stands are fitted and the handles are positioned inline with the
main chassis side member.
If an additional front mounted prop is fitted, ensure it is correctly stowed and
secured for towing.
Please remember brake linkage and handbrake must be free to move fully during
overrun braking when on the road so that breakaway cable can apply brakes if
trailer should part company with towing vehicle.
i) Check condition of breakaway cable. If frayed or kinked at all replace
immediately before use. Then connect breakaway cable to towing attachment on
towing vehicle. The cable must be free of knots.
j) Connect electrical plug to socket on rear of towing vehicle and check all lights are
fully operational.
k) Check the load is distributed to give the correct nose weight for the coupling, refer
to Section 3 for information on the hydratow coupling, a positive nose weight is
required to ensure stable towing. Also ensure nose weight is within limit of towing
vehicle.
l) When fitting the number plate ensure that if is fitted centrally beneath the number
plate lamp.

19
m) Ensure that the retaining clip on both rear prop stands is fitted and the handle is
positioned inline with the main chassis side member when in the raised position.
n) If towing with a car transporter vehicle, or any other vehicle, which has a long rear
overhang, extra forces can be applied to the coupling and towing device causing
rapid wear and damage. Please consult our Sales Department.
7.2 WHEN ON THE ROAD REVERSING –AUTO
REVERSING BRAKES
a) Simply reverse with towing vehicle having checked all is clear around you. Initial
resistance will be felt as brakes are applied on trailer and then automatically ‘roll-
off’, allowing reversing to continue. If reversing a heavy trailer up an incline, or on
grass or other slippery surfaces, wheel spin on the towing vehicle may occur, as
brakes initially come on.
b) If so, simply pull forward on to flat surface and recommence reversing operation
from there.
c) If trailer regularly has to be reversed up a steep incline, then an optional manual
override for such conditions can be offered.
7.3 PARKING –AUTO REVERSING BRAKED TRAILERS
a) Apply handbrake fully (if energy stores is fitted to rear of coupling then apply
further pressure to the handbrake to compress the spring which is fitted within the
energy store component). This ensures that should brake roll-off occur when a
trailer is parked with the rear facing down an incline that the brakes will
automatically be re-applied. . Please remember brake linkage must be free to
move fully during overrun braking when on the road, also handbrake so that
breakaway cable can apply brakes if trailer should part company with towing
vehicle. If the unit is fitted with a power assisted handbrake, then no further action
is required as the handbrake will automatically take up any further movement
should roll-off start to occur when parked on a slope.
b) Disconnect electrical plug from socket and store in safe position.
c) Loosen jockey clamp and lower jockey wheel to ground. Firmly re-righten clamp
(by hand). Press back trigger with thumb and lift handle on coupling head. At the
same time raise front of trailer by use of jockey wheel until head is fully clear of
ball on towing vehicle, if additional front mounted prop is fitted, ensure it is
correctly lowered and secured.
d) Disconnect breakaway cable from towing vehicle.
e) Drive towing vehicle clear of trailer. (in the case of a coupling fitted with an eye
follow above instructions except in respect of the final disconnecting of the towing
vehicle in which case the instructions supplied with the towing jaw or hook should
be used accordingly).
f) As extra security it is strongly recommended that the wheels of the trailer should
be chocked as an additional safeguard.
