1.In-line skate user manual

ATTENTION!!!
THIS MANUAL MUST BE READ CAREFULLY AND UNDERSTOOD BEFORE USING THE IN-LINE SKATES.
KEEP THE MANUAL FOR FURTHER REFERENCE.
IT IS SUGGESTED TO USE SAFETY HELMET AND WRIST,ELBOW AND KNEE
PROTECTORS
DESIGN OF IN-LINE SKATE
Each in-line skate consists of two elements: the boot and the lower part .The boot can be made
of plastic entirely or have its front part made of soft material. The lower part, called chassis can
be made of plastic or aluminum. The wheels are mounted to bearings, which are fixed to the
chassis with bolts and self-locking nuts.

 

 

Read the manual and remember the basic rules of safe skating

 

 

 

IN-LINE SKATING
Using in-line skate, due to constant moving at considerable speed. requires appropriate
technique of use, which provides safety for skater and the persons in their vicinity. Because of
the recreational purpose of in-line skates, it is suggested to use standard skating techniques
without any evolutions or jumps. It is highly recommended to use safety pads and helmets. The
skater must always be cautious during skating and adjust the speed to the level of their skills.
Appropriate ground surface is crucial it must be smooth, clean and dry. Slope terrain and
slippy, dusty, stony, wet ground should be avoided.
Before skating, ensure that all bolts are tightened.

 

BRAKING TECHNIQUES
If the in-line skates are equipped with brake:
The front part of the in-line skate equipped with brake should be slowly raised,( if both in-line
skates are equipped with brakes, any of them can be used for braking), then the brake should
be pushed firmly towards the ground.

If the in-line skates are not equipped with brake or it was removed:
“T-Braking Technique” is suggested but only for experienced skaters! The body weight should
be transferred to one foot, and then the second foot should be shifted after the first and set
perpendicularly. It looks like the letter“T”.

SIZE ADJUSTMENT

HOW TO DEFINE MODEL A AND B
A
1. Release the double-section buckles.
2. With the thumb press the button placed in the middle of the outer side of the chassis.
3. Push the front part of the boot to obtain the smallest size.
4. Push the button until you reach the desired size.
NOTE: You can lean the in-line skate against a stable object to make the adjustment easier.

B
1. Release the double section buckles.
2. Push the button placed on the front outer side of the boot. In one of the three blocking holes.
3. Pressing the button, set the desired size by placing the button in one of the three blocking holes

MAINTENANCE
Maintenance is very important for safe skating and dry prolonging the in-line skates'''' service life.
Each time after using the in-line skates, it is suggested to clean them carefully. Small stones
and other objects found between the wheels must be removed, Some elements like: brakes,
wheels or bearings are subject to wear. Their condition must be regularly checked and the
elements shall be replaced with new ones if necessary.

BRAKES
If the brakes do not work properly, it can be caused by their abrasion. The angle between the
lower part of the brake and the ground can indicate the abrasion, If it exceeds 40°,the brake
must be replaced.
Brake replacement:
1. Unscrew the axis bolt, which is located by the brake, using appropriate tool.
2. Remove the brake bracket from the chassis.
3. Remove the brake from bracket using a screwdriver.
4. Install new brake.
5. Install new brake bracket on the chassis and fix the axis bolt and the nut.
6. Make sure that the bolt is properly tightened.

The bolt should not be tightened too heavily.
For safety reasons it is suggested to use self-locking nuts only for once.

WHEELS
The durometer indicates wheels hardness the bigger number indicated, the harder the wheels
Are l. e. wheels 78A are softer wheels, 92A are harder wheels. Softer wheels adapt better to
the road and provide better traction. Harder wheels wear slower, provide lower traction and
poorer skating comfort.
The wheels dimensions are in millimeters.
60-64mm small wheels with low centre of gravity, help the beginners to keep stability.
70-72mm medium wheels, used for long distances and recreational skating.
76-82mm big wheels, used for fast skating, the most durable for arrange and experienced
Skaters.

The wheels wear during skating and shall be replaced from tine to time. The wear rate depends
on many factors, such as: skating style, surface, height and weight of the skater, weather, the
wheels material and their hardness.
Wheels wear faster on the inner side. The front wheels wear faster than the middle and back
ones . The wheels rotation is suggested after skating for about 70 km or in case of visible signs
of wear.

Wheels replacement:
1. Unscrew the wheels axis bolts with appropriate tool.
2. Remove the wheels from the chassis.
3. Remove the bearing from the wheel.
4. Put the bearing with sleeve into the wheel.
5. Install the wheels on the chassis and tighten the axis bolts.

The wheels fixing bolts should not be tightened too strongly.
For safety reasons it is suggested to use the self-locking nuts only for once.

Wheels rotation.
During rotation of wheels make sure that the most worn wheels will interchange its position with
the less worn one, Each wheel with bigger wear on the inner side shall be positioned in a way
that the more worn side faces the outside. It will provide uniform wear of wheels. The operation
should be realized according to the below scheme:
The wheels do not move freely.
To make the new wheels rotate freely ,they must be grinded-in. The bearing should be tightly
fixed and properly loaded for optimum efficiency. Also make sure ,that the bolts are not
tightened too strongly.

BEARINGS
The following types of bearings can be used:
608 z common bearings for beginners.
608 zz ABEC 1,3,5,7…..-very good bearing, long durability.
For ABEC, The bigger the number is, the better the bearing''''s precision and the material of
which it was made.

Qualified bears ensure fluent skating. All bearings were greased and do not require next
lubrication .Dusty, greasy and wet surfaces shall be avoided. Wet or damp bearings shall
be dried with clean cloth. Worn bearings must be replaced.

Bearings replacement
1. Remove the wheels from the chassis.
2. Remove the bearing from the wheel with appropriate tool.
3. Remove the sleeve and the second bearing.
4. Clean the bearing with dry cloth and replace it with a new one.
5. Insert the bearing into the wheel.
6. Insert the sleeve and the second bearing.

THE BASIC SAFETY RULES
■ Pay attention to the condition of the in-line skates.
■ Check and clean the bearing and wheels.
■ Make sure that the bolts are tightened properly.
■ Replace brakes when necessary.
■ Do not modify the in-line skate as it can cause danger to your safety.
■ Beginners should skate only on smooth surface.
■ Avoid high speeds.
■ Do not skate by holding any vehicles.
■ Use appropriate protective accessories.
■ Avoid skating on wet, greasy or stony surfaces.
■ Always pay attention to people around.

2.Can you explain the differences between the types of wheels and bearings?

Wheels - The numbers followed by the letters represent the size, in millimeters (mm), of the diameter of the wheel. The larger the wheel the higher the top speed; the smaller the wheel, the faster the acceleration and deceleration. The smallest wheels on our adult skates have been 70mm and some racing skates now fit up to 84mm. The wheel will also show a number followed by the letter (A). This is the hardness of the wheel referred to as the wheel''s durometer. The higher that number is, the harder the wheel. Soft wheels are used on smooth surfaces like indoor surfaces and asphalt in order to get added grip at higher speeds. A soft wheel can also be used on minimally ruff surfaces to increase shock absorption. The disadvantage of soft wheels used for outdoors will be an increased rate of wear. The disadvantage of using the harder wheels will be a less tacky material and hence, less grip, but with higher speeds because of less rolling resistance. For example, inline racers will use 82A or 84A to give maximum speed. Indoor hockey players will use 72A or 74A for maximum grip and maneuverability. General recreation skates will use 78A, a good combination of grip and speed. Another feature to consider is the shape of the wheel, called its profile. Racing wheels will be slightly pointed, to offer less rolling resistance and therefore will also have less grip. Those same hockey wheels from above will have a rounded profile to offer maximum contact no matter at what angle the wheel is touching the floor. Bearings - ABEC is an acronym for Annular Bearing Engineering Committee, which is a committee who rates bearings from manufacturers worldwide. The higher the number (ABEC bearings are 1, 3, 5, 7, etc in odd numbers) the tighter the tolerances in its manufacture. This will mean greater efficiency in the bearing, which will help maintain higher speeds. A higher ABEC rating does not mean a faster bearing, just that it is more efficient. Now in the market are Precision bearings that do not follow this rating. The will come as Titanium, Swiss or Ceramic. Since there is no rating to these bearings, they are difficult to compare. You can rest assured that these are excellent bearings and are in order from good to best (titanium, Swiss, ceramic). New to the market are microbearings, using a 688 size. These are also not rated but offer excellent performance. They have more ball bearings per skate bearing, which spreads out the skater’s weight more evenly allowing the bearing to operate more efficiently. They are much smaller and equal half the weight of the standard 608 size skate bearings. Also, because of their small size they will accelerate faster, a feature many people enjoy. The lubricant used within the bearing will also affect the speed. We use grease within the bearing, which offers the best protection against contaminants. Other lubricants, such as gels and oils will be faster, but would require more maintenance.
