2.4 DAILY WALK-AROUND INSPECTION

It is the ope rators respo nsibility to inspec t the ma chine

before the start of ea ch w orkda y. It is recomme nded that

ea ch o perator inspec t the ma chine before operation, even

if the ma chine has a lrea dy b een p ut into service under

a no ther op era tor. This Da ily Wa lk-Around Inspe ction is the

preferred method of inspection.

These chec ks are also to be performed a fter maintena nce

has been performed on the ma chine.

In a dd ition to the Da ily Wa lk-Around Inspec tion, be sure to

include the following as part of the daily inspection:

1. Overall cleanliness .

Chec k all stand ing surfac es for oil, fuel and hydrau-

lic oil spillage and foreign objects. Ensure overall

cleanliness.

2. P la ca rd s.

Keep all information and operating placards cleanand unobstructed. Cover when spray painting or

sho t blas ting to protec t leg ibility.

3. Ope ra to rs a nd S afety Manual.

Ensure a copy of this manual and the ANSI A92.5-

1992 Responsibilities, are enclosed in the manual

storag e box.

4. Ma c hin e Lo g .

Ensure a machine operating record or log is kept,

check to see that it is current and that no entries

have been left uncleared, leaving machine in an

unsa fe co ndition for operation.

5. Start eac h day with a full fuel tank.

TO AVOID INJURY, DO NOT OPERATE A MACHINE UNTIL ALLMALFUNCTIONS HAVE BEEN CORRECTED. USE OF A MALFUNC-TIONING MACHINE IS A SAFETY VIOLATION.

TO AVOID POSSIBLE INJURY, BE SURE MACHINE POWER IS"OFF" DURING WALK-AROUND INSPECTION.

NOTE: Check boom limit switches on upright for proper

operation and security, both visually and manually.

The lower switch cuts out drive speed when the

lower boom is above horizontal. The upper switchcuts out drive speed when the upper boom is above

horizontal. Only creep drive speed will continue to

function.

6. Check platform footswitch for proper operation.

Switch must be released to start engine and

depressed to operate machine.

7. Check that drive brakes hold when machine is

driven up a grade not greater than specified on the

serial number placard and stopped.

NOTE: On new machines, those recently overhauled, or

after changing hydraulic oil, operate all systems a

minimum of two complete cycles and recheck oillevel in reservoir.

8. Assure that all items requiring lubrica tion are se r-

vice d. Refer to Lubrica tion Cha rt, Fig ure 2-3, for spe-

ba ttery terminals a nd vent ca ps.

CAUTION

WHEN ADDING WATER TO BATTERIES, ADD

WATER UNTIL ELECTROLYTE COVERS PLATES.

DO NOT CHARGE BATTERIES UNLESS ELEC-TROLYTE COVERS THE PLATES.

NOTE: When adding distilled water to batteries, non-metallic

containers and/or funnels must be used.

To avoid electrolyte overflow, add distilled water to

batteries after charging.

When adding water to the battery, fill only to level

indicated or 3/8" above separators.

2. Remove all vent ca ps and inspect electrolyte level of

each cell. Electrolyte level should be to the ring

approximately one inch from top of battery. Fill bat-

teries with distilled water only. Replace and secure

all vent caps .

3. Remove bat tery cables from each ba t tery post one

at a time, ne ga tive first. Clea n ca bles with acid neu-

tralizing solution (e.g. baking soda and water or

am monia) and wire brush. Replac e ca bles a nd/or

cable clamp bolts as required.

4. Clean battery post with wire brush then re-connect

cable to post. Coat non-contact surfaces with min-

eral g reas e o r petroleum jelly.

cleaned, ensure all cables are properly positioned

and do not get pinched. Close battery co mpartment

cover.

6. Start hydraulic sys tem and ensure that it functions

properly.

Battery Charging, Daily.

NOTE: To avoid excessive battery charging time, do not

allow batteries to become completely discharged.

To avoid electrolyte overflow, add distilled water to

batteries after charging.

When adding water to the battery, fill only to level

indicated or 3/8" above separators.

1. Charge bat teries a t the end of each work day, or

when machine performance is significantly reduced

due to b atteries beco ming discharged.

2. Charge ba tteries in acco rda nce with the following

procedure:

a . Open bat tery compartment, and bat tery charger

compartment covers.

WHEN BATTERY CHARGER IS TO BE USED, CHARGING HAR-NESS MUST BE PLUGGED INTO A GROUNDED 110 VOLT RECEP-TACLE. IF RECEPTACLE IS NOT GROUNDED AND AMALFUNCTION SHOULD OCCUR, THE MACHINE COULD CAUSESERIOUS ELECTRICAL SHOCK.

b. Remove charging harness cable and connect to

a 110 volt receptacle.

c. Allow ba tteries to charge until ammeter on

cha rger, if equipped, is rea ding z ero (0). Normal

cha rging time is 8-10 hours.

NOTE: When batteries are completely charged, disconnect

charging harness cable from receptacle. Store

charging harness cable.

d. Ensure battery cables are positioned a nd are notp in c h ed . C lo s e a n d s ec u re a ll c o mp a r tmen t

doors.

3. The bat tery packs on each s ide of the frame a re

designed to be easily removed so that a machine

can have two sets of them in order to keep the

machine functioning longer. Disconnect the cable

quick connects, and remove the two clevis pins on

top of the frame. Now, using the forklift pockets

under the packs, have a forklift move them to a

plac e whe re they ca n be recha rged . The new ba ttery

packs can be installed by reversing the above pro-

cedure.
