General Safety Rules
WARNING: Read all instructions. Failure to follow all instructions
listed below may result in electric shock, fire and/or serious injury.
WARNING: To reduce the risk of injury, user must read
instruction manual.
1. Work area
a. Keep work area clean and well lit. Cluttered and dark areas
invite accidents.
b. Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust or fumes.
c. Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
2. Electrical safety
a. Power tool plugs must match the outlet. Never modify the
plug in any way. Do not use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs and matching outlets
will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded surfaces such
as pipes, radiators, ranges, refrigerators and wire fences. There
is an increased risk of electric shock if your body is earthed or
c. Do not expose power tools to rain, damp or wet conditions.
Water entering a power tool will increase the risk of electric shock.
Don’t use in rain.
d. Do not abuse the cord. Never use the cord for carrying,
3. Personal safety
a. Before you start the saw, make sure the saw chain is not
contacting anything. Stay alert, watch what you are doing and
use common sense when operating a power tool. Do not use a
power tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating
power tools may result in serious personal injury.
b. Use safety equipment. Always wear eye protection. Safety
equipment such as dust mask, non-skid safety shoes, hard hat,
rubber gloves, snug-fitting clothing or hearing protection used for
appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the off
position before plugging in. Carrying power tools with your finger
on the switch or plugging in power tools that have the switch on
invites accidents.
d. Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating part of
the power tool may result in personal injury.
e. Do not overreach. Keep proper footing and balance at all
times. This enables better control of the power tool in unexpected
f. Dress properly. Do not wear loose clothing or jewellery. Keep
479970-00 LP1000

Page 3
your hair, clothing and gloves away from moving parts. Loose
clothes, jewellery or long hair can be caught in moving parts.
g. If devices are provided for the connection of dust extraction
and collection facilities, ensure these are connected and
properly used. Use of these devices can reduce dust related
h. Maintain Appliance With Care - Keep cutting edge sharp and
clean for best performance and to reduce the risk of injury.
Follow instructions for lubricating and changing accessories. Inspect
appliance cord periodically, and if damaged, have it repaired by an
authorized service facility. Inspect extension cords periodically and
replace if damaged. Keep handles dry, clean, and free from oil and
i. Grip Saw Firmly - Hold the chain saw firmly with both hands
when the motor is running. Use a firm grip with thumbs and
fingers encircling the chain saw handles.
j. Power Supply - Connect chain saw to correct voltage, that is,
be sure that the voltage supplied is the same as that specified
on the nameplate of the tool.
4. Power tool use and care
a. Do not force the power tool. Use the correct power tool for
your application. The correct power tool will do the job better and
safer at the rate for which it was designed.
b. Do not use the power tool if the switch does not turn it on
and off. Any power tool that cannot be controlled with the switch is
dangerous and must be repaired.
c. Disconnect the plug from the power source when not in use,
before servicing, before making any adjustments, changing
accessories and attachments such as saw chain and guard or
storing power tools. Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d. When not in use, appliances should be stored indoors in a
dry, and high or locked-up place, out of the reach of children
and do not allow persons unfamiliar with the power tool or
these instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
e. Check Damaged Parts - Before further use of the appliance, a
guard or other part that is damaged should be carefully
checked to determine that it will operate properly and perform
its intended function. Check for alignment of moving parts, binding
of moving parts, breakage of parts, mounting, and any other
condition that may affect its operation. A guard or other part that is
damaged should be properly repaired or replaced by an authorized
service center unless indicated elsewhere in this manual.
f. Keep cutting tools sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier
to control.
g. Use the power tool, accessories and tool bits etc., in
accordance with these instructions and in the manner intended
for the particular type of power tool, taking into account the
working conditions and the work to be performed. Use of the
power tool for operations different from those intended could result
in a hazardous situation.
h. Do not operate a chain saw that is damaged, improperly
adjusted, or is not completely and securely assembled. Be sure that
the saw chain stops moving when the trigger is released.
i. Use extreme caution when cutting small size brush and
saplings because the slender material may catch the saw chain
and be whipped toward you or pull you off balance.
j. Carry the chain saw by the front handle with the saw stopped,
finger off the switch, the guide bar and saw chain to the rear.
k. Maintain Chain Saw With Care - Inspect chain saw cords
periodically and if damaged, have repaired by authorized
service facility. Keep cord clear of the chain and operator at all
479970-00 LP1000

- This electrically powered saw is classified by CSA as a Class 2C
saw. It is intended for infrequent use by homeowners, cottagers,
and campers, and for such general applications as clearing,
pruning, cutting firewood, etc. It is not intended for prolonged use.
Prolonged periods of operation can cause circulatory problems in
the user's hands due to vibration. For such use, it may be
appropriate to use a saw having an anti-vibration feature.
Reduced Kickback Chain - Designed with a contoured depth gauge
and guard link which deflect kickback force and allows wood to
gradually ride into the cutter.
Electrical safety
This tool is double insulated; therefore no grounding wire is
required. Always check that the power supply corresponds to the
voltage on the rating plate.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber. (CCA)
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to
filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the
skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse
dust, which may cause serious and permanent respiratory or
other injury. Always use NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure. Direct particles away
from face and body.
CAUTION: Wear appropriate personal hearing protection during use.
Kickback Safety Features
Guard against kickback. Kickback is the upward motion of the guide
bar that occurs when the saw chain, at the nose of the guide bar,
contacts an object. Kickback can lead to dangerous loss of control of
the chain saw.
WARNING: The following features are included on your Alligator
LopperTM to help reduce the hazard of kickback; however such
features will not totally eliminate this dangerous reaction. As a chain
saw user do not rely only on safety devices. You must follow all
safety precautions, instructions, and maintenance in this manual to
help avoid kickback and other forces which can result in serious
Top Jaw - This has been designed specifically to cover the tip of the
chain bar where the danger zone for kickback occurs. In the event
of any kickback the guard also helps prevent the chain coming into
contact with the operator.
Reduced Kickback Guide Bar - This has been designed with a
small radius tip which reduces the size of the kickback zone on the
bar tip.

resulting from a possible electrical insulation failure within the tool.
REPLACEMENT PARTS: When servicing all tools, USE IDENTICAL
REPLACEMENT PARTS. Repair or replace damaged cords.
Extension Cord
Polarized Plugs
To reduce the risk of electric shock, this equipment has a polarized
plug (one blade is wider than the other). This equipment must be
used with a suitable polarized 2 wire or 3 wire extension cord.
Polarized connections will fit together only one way. Make sure that
the receptacle end of the extension cord has large and small blade
slot widths. If the plug does not fit fully into the extension cord,
reverse the plug. If it still does not fit, obtain a suitable extension cord.
If the extension cord does not fit fully into the outlet, contact a
qualified electrician to install the proper outlet. Do not change the tool
plug or extension cord in any way.
Make sure your extension cord is in good condition. When using an
extension cord be sure it is heavy enough to carry the current your
product will draw. An undersized extension cord will cause a drop in
line voltage resulting in loss of power and overheating. The following
table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The
smaller the gage number, the heavier the cord.

Chain tension adjustment (fig. A)
WARNING: Before chain or other adjustments, make sure
that the tool is switched off and unplugged.
If the chain can not be correctly tensioned, it may need to be
replaced. Contact your nearest service center.
The product comes ready assembled. However we recommend that
you check the tension of the chain, and chain retention nuts before
use and if required adjust.
Checking and adjusting the chain tension (fig. A)
Assembling the chain bar and chain (figs. C&D)
To tension the chain slacken the two chain cover retention nuts (11)
with the wrench (2) and the chain tensioning device will push the
chain bar out, setting the correct tension. Retighten the two
retention nuts (11) securely.
Check that the correct tension has been set by lightly pulling on the
chain. The tension is correct when the chain snaps back after being
pulled 1/8” inch (3 mm) away from the guide bar. There should be
no "sag" between the guide bar and chain on the underside.
Note: Do not over tension the chain as this will lead to excessive
wear and reduce the life of the bar and chain. It will also lead to
reduced product performance.
Note: With first use and when the chain is new, check tension
frequently as a new chain stretches slightly.
WARNING: Before chain or other adjustments, make sure
that the tool is switched off and unplugged.
WARNING: Always wear protective gloves when installing or
removing the saw chain. The saw chain is sharp and can cut you
when it is not running.
- Ensure the operation is carried out on a firm surface.
- Open the handles and pull back the top jaw (6).
- Insert the chain bar (8) into the space between the chain
tensioner and the first bolt, angle the chain bar down over the bolts.

Pull the chain bar and chain back, engaging it in the groove in the
chain bar and then over the sprocket (14) positioning teeth in the
correct position on the sprocket.
- Replace the chain access cover (12) and retention nuts (11)
tightening securely.
- Before first use and every ten minutes of use you must oil the
product with the recommended chain oil. Open the oiling cover (10)
and insert the bottle into the oil filling hole (15) apply pressure to the
bottle once to dispense oil.
- This should be adequate for about 10 minutes of cutting
depending upon cutting speed and type of wood.
- The hole feeds the oil through to the chain onto the chain bar and
an excessive amount of oil applied to the unit could mean the oil
drips from the unit around the jaw area. This is normal and is
nothing to be concerned about.
Never operate a chain saw that is damaged or improperly adjusted or
that is not completely and securely assembled. Be sure that the saw
chain stops moving when the power control system triggers are
released. Never adjust the guide bar or saw chain when the engine is
WARNING: Let the tool work at its own pace. Do not overload.
- Carry out regular cleaning of the unit as described in the
maintenance section and in particular cleaning inside the chain
access cover.
- The lower guard (7) and top jaw (6) are designed to close when
one of the handles is released or when the piece of branch being
cut has been cut. If this does not occur, discontinue use of the tool
and remove the power cord. Check if any debris is blocking
movement. To help in this process it may be necessary to remove
chain access cover(12). If on assembly the problem is still present
take the unit to a service center.
Switching on and off (fig. G)
For your safety, this tool is equipped with a double switching
system. This system prevents starting the tool inadvertently.
A chain saw is intended for two-handed use. Serious injury to the
operator, helpers, and/or bystanders can result from one-handed
Switching on
Ensure a firm grip on the handles and then squeeze both switch
actuators to switch the unit on.
Note: Both switches must be activated for the product to be used.
Do not force the tool - allow it to do the work. It will do a better and
safer job at the speed for which it is designed. Excessive force will
stretch the chain.
If the saw chain or bar becomes jammed:
- Switch the tool off.
- Disconnect the tool from the power supply.
- Open the cut with wedges to relieve the strain on the guide bar.
Do not try to wrench the saw free. Start a fresh cut.
Extension Cord (fig. E)
To reduce the risk of disconnection of appliance cord from the
extension cord during operation make a knot as shown in Figure E on
page 8.
NOTE: Always keep the cord away from the cutting area and position
the cord so that it will not be caught on branches, and other material,
during cutting.
Trimming branches
- Make sure the tool is running at full speed before making a cut.
- Hold the tool firmly in place to avoid possible bouncing or
sideways movement of the tool.
- Guide the tool using light pressure.
- Always cut down from the top. This way you will avoid pinching
the saw chain.
Oiling (fig. F)
