•
T – Tire ( check pressure, thread, ply, spare tire)
H- Horn (Check if functioning, adjust sound if necessary)
E- Engine ( check for any leak or sign of overheating)
B- Battery ( check solution, cables connection, terminals )
L –Light (check all lights if functioning)
O- Oil ( check oil level or leak with in engine parts)
W –Water ( check level in radiator)
B- Brake System ( Check brake fluid level, brake lining)
A – Air ( Pressure ( check for air leak
G – Gas or Fuel Gauge ( Check fuel level, all if properly
functioning)
3. Cooling System
• Cooling System – maintains the efficient running
temperature in all running speed and driving conditions.
HOW?
• Radiator is free from any dirt and corrosion and no means
of any leakage.
• Good condition and Correct belt deflection (7-11 mm).
• Radiator hoses are in good condition/hose clamps are
properly fit.
• Regular changing of coolant or water.
• Thermostat is in good condition.
• Fan blades are in good condition.
4. Lubricating System
• Lubricating system –lubricates moving parts in order to
minimize wear and power loss due to friction and
extending engine’s life.
HOW?
• Making visual check – oil level must be at full level but see
to it that vehicle is on flat/plain surface.
• Oil must have no contamination of dirt.
• Change engine oil in every 5,ooo km or maximum of 6,000
km.
• Change oil filter
5. Fuel System
• Fuel System- supplies combustible mixture of
air and fuel.
• How?
• No leakage at any fuel lines or fitting.
• No leakage in intake manifold
• No clogged up in air cleaner.
• No clogged up in fuel filter
• Injectors can deliver proper spray of fuel.
7. Battery
• Battery – supplies electrical energy to starter motor
during cranking. It has a minimum cranking speed of
250 revolution per minute (rpm).
• HOW?
• Battery terminals, clamps should free from any means
dirt's or corrosion.
• Battery cables are properly tighten.
• Good grounding connection.
• Maintain proper level of battery solution add distilled
water if level is low.
8. Brake System
•
•
•
•
•
•
•
•
•
Brake system –used to slow or stop the vehicle in motion.
How?
Proper fluid level, it must be at maximum level.
Brake lines and Fluid must have no leakage ay any point of
connections.
Brake shoes are properly adjusted.
Hydrobox and vacuum hose must be in good condition and
properly fitted.
Rubber caps must be in good condition.
Brake drum surface must in good condition.
Used DOT 3 Brake fluid and must not be contaminated from
any petroleum products or other liquids.
9. Lighting, Warning Systems
• Lightings- used to illuminate the area ahead of the
vehicle respectively.
• Warnings should indicate properly and respectively.
• Oil indicator light should indicate when the ignition
switch is ON and OFF when the engine is running
already.
• Charging light indicator – should indicate when the
ignition switch in ON and OFF when the engine is
running already.
• Temperature gauge must be in good condition.
• Wipers and other accessories must be in good
condition.

11. A:
Ang pressure ng gulong ay nasa “standard settings”.
B:
Ang pressure ng gulong ay mas mababa ng sampung
porsyiento (10%) kaysa sa standard settings.
C:
Ang “pressure” ng gulong ay mas mababa ng tatlumpong
porsyiento (30% kaysa sa standard settings”.
Kung ang “pressure” ng gulong ay mas mababa ng
sampung porsyiento kaysa sa “standard setting”, ang
kunsumo ng krudo ay tumaas ng hanggang apat na
porsyiento. At kapag ang “pressure” naman ay bumaba ng
hanggang tatlumpong porsyiento kaysa sa “standard
pressure”, ang pagtaas naman sa kunsumo ng krudo ay
aabot ng hanggang labindalawang porsyiento.
12. KULANG ANG
“AIR PRESSURE”
MAGKAKAROON
NG
“SHOULDER WEAR”
Ito ay dahil mas lumalapad ang parte ng gulong
na lumalapat sa kalsada kapag ito ay kulang sa hangin,
Dahil dito ay mas lumalaki ang “roling friction”.
13.
TOE – IN
The front wheel are
closer together than
the back wheels.
Excessive toe-in
causes rapid wear on
the outside shoulder
of the tire.
Set as close to zero as
vehicle manufacturer’s
recommendations allow
In loaded condition
14. Camber
• Camber- tilting top of the wheel from viewed
vertically.
• Positive camber- when top of the wheel is
tilting outward.
• Negative camber – when top of the wheel is
tilting inward.
15. Clutch
• Clutch- is used to engage and disengage the power
from engine through transmission.
• It is used to used temporarily uncouple the engine and
transmission so that gears can be shifted.
• HOW?
• Hydraulic clutch must properly adjusted.
• And has no any means of leakage.
• Clutch disc must be in good condition as well as the
clutch pressure plate so that it can transfer power
without slipping, accurately, quickly and entirely.
16. Manual Tranmission
• It is an assembly of gears needed to move the
vehicle under a variety of load and road
condition.
• Gear oil must be in proper level.
• It is advisable to change gear twice a year.
• Use SAE 9O for light duty vehicle
• Use SAE 140 for heavy duty vehicle.
• It should has no leakage.
