Battery Safety Guidelines
Used correctly, domestic batteries are a safe and dependable source of portable
power. Problems can occur if they are misused or abused – resulting in leakage
or, in extreme cases, fire or explosion.
Please follow these simple guidelines to eliminate the possibility of such problems:
Only use good qualityAlkaline batteries. To fit the batteries, refer to the instructions and
the diagram inside the battery compartment. Make sure battery compartment lid is
firmly secured.
Do not use re-chargeable batteries.
Do not short-circuit battery terminals.
Always take care to fit batteries correctly. Observe the plus and minus signs on
the batteries and in the battery compartment.
Always replace the complete set of batteries at one time, taking care not to
mix old and new batteries or batteries of different types.
Always store unused batteries in their packaging and away from metal objects
which may cause short-circuits.
Always remove dead batteries from equipment. Remove batteries from
equipment which you know will not be used for a long time, otherwise the batteries may
leak and cause damage.
Always supervise children if they are replacing batteries themselves to ensure
these guidelines are followed.
Always make sure that battery compartments are secure.
Never dispose of batteries in a fire as this can cause them to explode.
Never attempt to recharge ordinary batteries as this may cause fire or explosion.
Waste electrical products should not be disposed of with household waste.
Please recycle where facilities exist. Check with your Local Authority or retailer
for recycling advice.

Assemble the engine turbine/
compressor blades unit into the
outer engine casing half.
Assemble the inner engine casing
half onto the outer engine casing
half aligning the screw holes.
Note: The inner casing half has a
locating lug to ensure correct
positioning into the inner engine
nacelle half.
Secure the two engine casing
halves with four screws, and at this
stage check that the fan blades spin
freely by blowing on them.
NOTE: If they do not spin freely, it is
because the fan blades have been
fitted too tightly together on the
spindle, so remove the casing and
gently ease the fan blades further
apart.
Blades must have “end float” when
in position.
