Riflescopes
Maintaining you riflescope:
Your scope is a precision instrument that deserves a high level of care. Do not attempt to
disassemble or clean the scope internally.
Keep the protective lens covers in place when the scope is not in use.
The external optical surfaces should be wiped clean occasionally with the lens cloth provided or
an optical quality lens paper. Remove any external dirt or sand with high pressure air and a soft
brush to avoid scratching the lens finish.
Wipe the scope with a damp cloth, then with a dry cloth, then go over the metal section of the
scope with a silicone cloth in order to protect the scope against corrosion.
Always store the scope in a moisture-free environment. Avoid storing the scope in places such as
the passenger compartments of vehicles on hot days as the high temperatures could adversely
affect the lubricants and sealants. A vehicles boot, a gun cabinet or a cupboard is preferable.
Never leave the scope where direct sunlight can enter either the objective or the eyepiece lens as
damage may result from the concentration (burning effect) of the suns rays.

Reticle Illumination
10
The Sidewinder has a precision glass etched illuminated reticle fitted as standard. The reticle can
be illuminated either red or green. There are five illumination brightness settings for each colour.
7
The fist three settings (1-3) are dedicated night settings. These have been specifically designed
for shooing in low light conditions when little illumination is required.

RIFLESCOPE FEATURES
The remaining settings (4&5) are specifically deigned for daytime shooting. These settings are
designed for normal daytime conditions being very useful when shooting into dark backgrounds
such as hedgerows. Please note some settings may not be visible during very bright daylight.
The reticle illumination adjustment dial is positioned on the side wheel focus knob. To alter the
illumination, rotate the knob to the desired setting.
6
The first sign of the battery becoming low is indicated by thegreen illumination ceasing to work. At
this stage, you should consider replacing the battery. The battery compartment is positioned on
the end of the illumination control. Replace the battery using a CR2032 3V Lithium battery (Hawke
code BA7800)

Zoom (magnification)
INSTRUCTIONS FOR USE
Sidewinder riflescopes feature a true 4X optical system allowing a magnification increase of 4X.
To alter the magnification of your Sidewinder riflescope, rotate the zoom ring positioned forward of
the eyebell.
Please note: although the zeroed Point Of Impact will not change when you change the
magnification, other additional aim points will alter due to the reticle being positioned in the
second focal plane.
ZOOM
Sunshade
High performance lens coatings are used on all of the Sidewinder lenses.Internal tubes are
coated to ensures that any stray light/reflections are kept to a minimum.
However, on extremely sunny days, or when shooting over highly reflective surfaces (standing
water / snow) we recommend using the supplied 100mm long sunshade.
To use, simply screw the threaded end into the objective bell of the rifle scope.
Screw-In Lens Covers
The Sidewinder is supplied with screw-in lens covers, designed to protect the lenses when not in
use.
When fitting the sunshade the screw in
lens covers need to be removed first.
The screw-in lens covers will not fit the
sunshade.
WARNING: NEVER LOOK AT THE SUN
WITH THIS RIFLESCOPE - IT MAY PERMANENTLY DAMAGE YOUR EYES.
STEP 1 - Ocular Lens Adjustment:
Because each human being has different eye characteristics, riflescopes are made to have
adjustable eyebells. The Sidewinder 30 range features a fast focus ocular adjustment with the
additional feature of a lock ring.
UN-LOCKED
To focus your personal eye characteristics to the riflescope, thus giving a crystal clear picture of
the reticle, carry out the following adjustment.
Hold the scope about three or four inches from your eye and look through the eyepiece at a
featureless, flatly lit, bright area such as a wall or open sky. If the reticle is not sharply defined,
loosen the eyebell lock-ring and turn the eyepiece (either direction) a few turns. Quickly glance
through the scope again. If the focus has improved, but is still not perfect,
continue focusing. When the reticle appears in sharp focus, retighten the lock-ring. The lock ring
is a unique feature to the Hawke SideWinder, that helps prevent unnecessary adjustment either
out in the field or by a third party
LOCKED
STEP 2 - Mounting the riflescope:
CAUTION: Be sure that the firearm is NOT loaded. Always practice safe firearms handling
Always check that the diameter of the riflescope body tube matches the diameter of the scope
mounts that you wish to use. The Sidewinder has a 30mm ‘mono’ body tube, therefore 30mm
mounts are required.
Purchase the best mounts that you can afford making sure that the base of the mount will fit your
rifle.
Hi-recoil rifles, such as spring air rifles may require mounts to be fitted with recoil stop pins.
Fix the mounts to the rifle mount base - do not tighten the mounts. Lay the riflescope into the
mounts. The scope should be mounted as low as possible without touching either the barrel or
the receiver. Before tightening the mount rings, look through your scope in your normal shooting
position. Adjust the scope (either forward or backward) until you find the furthest point forward (to
ensure maximum eye relief) that allows you to see a full field of view. Rotate the scope in the rings
until the reticle pattern is perpendicular to the bore and the elevation turret is on top. Then
tighten the mounting screws, tightening each side evenly.
ARNING: AVOID OVER-TIGHTENING THE RINGS. THIS CAN DAMAGE THE SCOPE
W
AFFECTING PERFORMANCE OR RENDERING IT INOPERABLE.
BE SURE THAT THE SCOPE IS MOUNTED FAR ENOUGH FORWARD - ITS REARWARD
MOTION MAY INJURE THE SHOOTER WHEN THE RIFLE RECOILS.

STEP 3 - Zeroing the riflescope
WARNING: ALL SHOOTING SHOULD BE CARRIED OUT AT
AN APPROVED RANGE OR OTHER SAFE AREA.
EYE AND EAR PROTECTION IS RECOMMENDED
DURING THE PROCEDURE.
The Sidewinder 30 is fitted with 1/4 MOA
push/pull locking turrets.
ELEVATION TURRET
WINDAGE TURRET
1/4 MOA Turrets
Each click of adjustment is known as a 1/4 minute of angle (1/4 MOA). This means that one click
of movement closely equates to 1/4” of movement on a target set at 100 yds distance. Therefore
at different ranges, each click of adjustment changes:
50 yds = 1/8” 100 yds = 1/4” 200 yds = 1/2” 300 yds = 3/4”
The Sidewinder turrets are factory preset in the centre of the FOV (Field of View). The reticle
needs to be adjusted to the ‘zero’ distance of the rifle on which it is mounted.
Before adjusting the turrets, you must first unlock them. This is done by pulling them out, so that
they click whilst they rotate. The turrets can than be adjusted until they are on zero. To lock the
turrets, simply push them back down.
LOCKED
When a satisfactory zero is achieved, the turrets can be reset. To do this, simply loosen the hex
screw on the top of the turrets and then pull the turrets up to their furthest extent. The turrets will
then rotate without clicking. Adjust to the ‘0’ zero point, push the turrets down to locate into the
locked position and re-tighten the hex screw.

OPERATION AND FEATURES
To get the most out of your new riflescope we recommend that you read the following, in
addition to the ‘instructions for use’ so you fully understand all of the features and how they
operate.
- Side Wheel Parallax - Big Wheel Pointer - Zoom Magnification
- Sunshade and lens covers - Reticle Illumination - Reticle types -
- BRC Software
To be parallax free, the target must be at the distance equal to the scope focus. Any other
distance will cause parallax error, which manifests itself as apparent movement of the reticle
against the target. The Sidewinder is equipped with side wheel parallax. To adjust the range
setting of the scope, rotate the side wheel focus knob to the distance you want to shoot. When the
image is sharp, the correct parallax setting is achieved. On higher magnification it is easier to
determine whether the image is in or out of focus. Once the image is in focus the distance can be
read on the side wheel scale. This can successfully be used to ‘range find’ the target.
For more accurate range finding and more sensitive operation, the supplied 100mm big wheel can
be used. The scale on the Big wheel is spaced out more, therefore it is easier to determine the
exact distance/parallax free setting.
Installing and Resetting the Scale on the Big Wheel
To install the big wheel, first of all you need to loosen the three screws on the rear of the wheel and the
three hex (grub) screws on the inner ring. DO NOT FULLY REMOVE THE SCREWS. Once these screws
are loosened the inner rubber ring should rotate. Please ensure for set–up that it is loose and rotating.
Align the ‘teeth’ of the side wheel focus knob and
the reticle brightness control. Then slide the big
wheel completely past the brightness control and
onto the side wheel focus knob.
When located, rotate the scale until the yardage on
the big wheel matches the scale on the inner focus
knob.
Once aligned carefully remove the big wheel,
keeping the scale in the same position Tighten up
the three screws on the rear of the wheel.
Position the wheel back on the focus knob and
tighten the three small grub screws. Please note
these should not be over tightened.
To read the scale on the Big Wheel we recommend
using the Big Wheel pointer. To install, place the
pointer around the body tube, at your preferred
position.
