INTRODUCTION
The Nano / 830P (referred to as “the machine”in this manual) is designed
to be a simple, quick and safe powered alternative to a portable
scaold tower, podium or a step ladder, for internal construction site
and maintenance applications. It can be used in applications where
previously portable scaolding towers are erected on castors, and moved
about on hard level surfaces. These types of tower are open to incorrect
assembly, and are dicult and time consuming to work from. The
Nano / 830P eliminates many of the risks associated with portable
scaold towers.
It is suitable for any application provided it is used within its specied
operating parameters. If used for applications such as sand blasting,
welding, paint spraying or with any other hazardous materials, then
measures must be taken to ensure it does not become damaged in any
way which may impair safety, or reliability. Additional protection for the
operator may be required in some cases, which is the responsibility of the
operator and/or the operator’s employer.
The purpose of this manual is to provide essential basic information
required to operate and maintain the machine.
This is not a workshop manual. Please contact the manufacturer or
their agent for specic operation or maintenance information if in
doubt.
The health and safety of the operator or maintenance technician is the
responsibility of the individual and/or their employer and not Power
Towers Ltd.
It is essential to be familiar with the operating, maintenance and safety
guidelines contained within this manual prior to the operation of the
machine.

OPERATING PROCEDURES
It is the owners and/or the users responsibility to ensure that the machine is maintained
and operated in accordance with the operation and maintenance procedures contained
within this manual.
It is essential to be familiar with the correct operating procedures as outlined in this manual
The operator must have adequate training for this type of platform.
The machine is tted with a safety harness point as standard. If the operator chooses to
wear a safety harness, an approved‘fall restraint’ type harness should be worn.
Operating procedures are divided into three key areas:
1. Pre-operation checks.
What to do before operating the machine.
2. Normal operation.
How to use the machine safely.
3. Emergency operation.
How to lower the machine without power or in the event of
operator incapacity.
There is no specic legal requirement to wear a safety harness. However,
there is an employers’ requirement to ensure the correct equipment is
used for a task and that it is used correctly and safely. For this requirement
to be met, a risk assessment should be conducted to assess the potential
risks and if an increase in operator safety can be achieved with a safety
harness, then use a‘fall restraint’ type harness only.

EMERGENCY LOWERING OPERATION
Never attempt to recover the machine/operator if there is any
possibility the machine is contacting any live wiring/cabling and is
therefore potentially ‘live’.
The Emergency Lowering Procedure is for lowering the platform from
height in case of platform control failure or operator incapacity and
for no other purpose.
To lower the platform:
1. Locate emergency lowering valve at base of machine (see Pic, right).
2. Push, twist 90 degrees anti-clockwise and release the knob.
The platform will lower. Pushing and twisting the knob clockwise
will stop the descent at anytime.

Please note that whilst the machine is extremely simple to
maintain, all work must be carried out by a competent person.
When removing checkerplate cover for maintenance purposes,
rst switch o by depressing the emergency stop/battery isolator
button located at the base of the machine. Use appropriate
safety/personal protective equipment where necessary.
DAILY MAINTENANCE
Tilt cage by releasing gate latch on cage mount (see pic). Pull cage
frame from gate end and cage will lift and tilt assisted by gas strut.
Ensure gas strut is fully extended and that the safety chock is in place.
You can now access the powerpack housing. Unscrew the black
retaining knobs and lift out the checkerplate cover.
1. Check Battery Electrolyte Level: (Not applicable to AGM Batteries)
Remove battery cover and battery caps. Ensure the electrolyte
covers the plates by no more than 1mm – 2mm. Replenish with
distilled water to this level, only if the electrolyte level is below
the top of the plates.
2. Check Hydraulic Oil Level:
Ensure the tank is not overlled. The level must only be checked
when the machine is in the transport position. The correct level
in this condition is approximately 3/4 from the base of the tank,
as indicated by the line.
3. Ensure there is no obvious mechanical damage to the handrails,
entrance gate, post or structure of chassis. Also check the castors
and wheels are undamaged, rotate freely and are secured
to machine.
4. Check hydraulic connections around the pump and base of
cylinder are tight and undamaged.
5. Check the spirit level to ensure it is clearly legible and
undamaged.
6. Check all functions operate correctly including movement alarm
and emergency stops.
7. Ensure mast surfaces are clean and not greased.
WEEKLY MAINTENANCE
Check battery terminal connections are tight.
MONTHLY MAINTENANCE
Check Battery Specic Gravity:
On a monthly basis check the specic gravity in each of the battery
cells. When a battery is correctly fully charged the specic gravity
should be 1.27 - 1.3. The specic gravity reading should be equal
across the cells, if not repeat the full charge cycle.
Check rollers and mast surfaces for damage. Ensure brushes are tted
correctly and brush against mast surface.

HYDRAULIC OIL
The hydraulic oil must be replaced on an annual basis. If the oil is not
replaced, then premature wear and failure of components will occur.
To drain the hydraulic tank, the mast must be in the transport position,
and the platform tilted to allow access to the motor/pump unit. The
only practical method to remove the oil from the tank is to use a syringe
suitable for hydraulic oil, which are easily obtainable, or a vacuum system
for hydraulic oil. The hydraulic steel pipe connection to the cylinder must
not be disconnected, unless by a competent person. If the connection
has been disconnected, then a full pressure test of the system must be
conducted prior to placing the machine back into service. No leaks must
be evident when the pressure test is conducted.
Rell with grade 32 mineral oil.
WHEELS AND CASTORS
It is absolutely essential that the wheels and castors are maintained in
good condition at all times, for two reasons:
The rst is that they act as the stabilisers, and whilst their load capacity
is over rated for the application, any failure could result in a serious
accident. Secondly, if the bearings become tight, then it will make the
machine dicult to manoeuvre.
A measure of horizontal push force can simply be made to determine the
condition of the wheel bearings. On a at smooth surface the machine
should move with a force of 9 – 10 kg at the mid guard rail height. The
maximum allowance is 20 kg.
Obviously this force is dependant upon the surface and gradient, but the
above is the recognised method of measurement, in accordance with HSE
guidelines.
Check rear wheels to ensure retention circlip is securely tted to end of
stub axle and plastic cap is tted over it.
MOTOR CONTACTOR SOLENOIDS
When conducting the six monthly LOLER inspection, check the correct
functioning of the two motor contactors.
Fit new contactors after every three years.
SUZI CABLE CONNECTOR PLUG MAINTENANCE
In order to ensure the reliable and correct operation of the machine it is
highly recommended that on a six monthly basis the connector plug be
separated and the condition of the connector plugs pins be noted and an
anti-corrosive spray be applied before reassembly.
Locate the plug on the end of the wire from the suzi cable and holding
both the wires and the rubber body of the connector plug, pull the two
halves apart. The plugs cans sometimes be dicult to separate and it may
be found that rolling back the outer boot prior to pulling the plug apart
can help.
Once separated look at the condition of the pins. If found to be corrosion
free then spray the pins and sockets with Ambersil S4. Hold each half of
the connector plug vertically and spray a liberal amount of the anti-
corrosive grease into the plug and pins and allow to drain into the back
of the plug body. The spray can also be applied to the rubber boot. Re-
assemble the plug.
If the pins are found to have corrosion they must be replaced. In this case
please refer to Power Towers technical department for assistance.
When replacing components for any reason, only use OEM specication
parts, either supplied from the manufacturer or authorised in writing
by the manufacturer. Warranties and design approvals will be void if
alternative components are tted.
It is essential to obtain manufacturer’s approval of any alteration
which might aect stability, strength or performance in writing before
proceeding.

CASTOR SAFETY & MAINTENANCE
14
CASTOR SAFETY & MAINTENANCE
In order to ensure the castors are maintained in serviceable and safe
condition, regular inspection is required, especially where arduous
conditions are known to be involved or there is a suspicion of misuse or
abuse. The other key element to ensure is in safe serviceable condition, is
the castor xing bolt, the condition of which can usually be determined
from the condition of the castor bracket.
The castor is highly rated for the application so if visible distortion is
evident a signicant impact will have occurred and under these conditions
the castor and xing must be replaced.
Typical signs of impact which would require castor and xing replacement:
It may be thought feasible to repair the castor in a number of these
instances, but serious structural damage will have occurred to the head
bearing and castor assembly as well as possibly damage to the main
xing bolt. THE CASTOR AND FIXING BOLT MUST BE REPLACED.
When inspecting a castor in order to
determine its serviceability, pay particular
attention to the head swivel bearing
(compare to a new one if possible) and the
boss/rivet which goes through the centre
of the swivel bearing and which clamps the
assembly together.
If the castor is in sound condition,
free from distortion then it may be adequate
to only replace the main xing
bolt with one of a higher tensile
strength, along with a spacer
washer that enables a higher
bolting torque to be applied.
This will improve the reliability of
the x, but will not increase the
strength of the castor assembly.
The new xing nut and bolt are to
be re-torqued to 80Nm.
In order to replace the xing bolt, the wheel axle
bolt, half nut and star washer will rst need to be
removed, along with the central bushing tube
and M12 end washers. This enables the wheel to
be removed so that the castor xing bolt can be
replaced. When retting the wheel, the axle bolt,
half nut and star washer, must be replaced with
OEM specication new parts and re-torqued to
40Nm (Pic A). Ensure the axle tube and assembly is lightly greased to
ensure a smooth action when operating the foot brake.
Power Towers Limited strongly recommends replacing any castor
assembly that is over 3 years old with a new one.

MAINTENANCE PROCEDURES
MAST MAINTENANCE
Essentially the mast is maintenance free. The mast sections run on
maintenance free rollers, and on the outer mast surface where the
roller runs, a brush is tted to keep the mast surface clean, preventing
debris picking up in the roller. In addition to these rollers, there are
6 external plastic screws tted, which act to hold the mast sections
together in torsion. These screws are tted with M24 lock nuts and
can easily be identied at the lower end of the mast sections. Inside
the mast there are additional wear pads and rollers, which can be
accessed from the top of the mast. These items are not adjustable,
and it is very unlikely that any wear will occur.
The mast is raised and lowered with a multistage hydraulic piston,
which raises the outer mast section rst, followed by the middle mast
section. When the mast is lowered, the sections close in the reverse
sequence i.e. the middle section and outer section close together
until the bottom of the middle section contacts the lower rest buers,
and the outer section continues to close over the middle section. It is
essential the mast closes in this sequence.
To ensure the mast sections move in the correct sequence, and do
not bind, ensure the wear screws are not over tightened as follows.
Ensure the gap between the overlapping mast section and the inner
mast section is even on both sides. The distance is approximately
12mm, but may vary slightly due to manufacturing tolerances.
Loosen the wear screw lock nut and turn the screw until it just
contacts the inner mast surface. Do not force the screw. Tighten the
locknut using caution not to shear the screw thread. Raise and lower
the mast to check it does not bind. (See picture).
In practice, it is far more likely that the screws may wear so an
excessive gap between the mast section and the wear screw
develops. This will be evident by free sideways movement of the
platform. If this free movement is thought to be excessive, check the
gap between the screw and the mast with a feeler gauge. The correct
gap should be no more than 0.2mm, although the mast is serviceable
with a gap up to 0.5mm.

STORAGE
If the machine is to be taken out of operation for a period longer than
one month, the following precautions should be taken.
Ideally, the battery charger should be switched on. The charger
has an inbuilt maintenance mode, and will maintain the battery in
good condition indenitely. If a Lead-Acid battery is tted then the
electrolyte level must still be checked periodically (not required
if AGM battery is tted). If this is not practical, then the charger
should be switched on once a week for half an hour. This is especially
important in cold conditions.
The hydraulic oil must be replaced (recommended after 3 months of
non-use) as for the procedure in the Maintenance Procedures section.
If the storage period is for an undetermined period then it is
advisable that the battery be removed and stored in a secure battery
storage container. We would also advise that all external electrical
and hydraulic connections be wax coated to prevent corrosion.
