General Information - Standard Workshop Practices
Des cript ion and Operat ion
Vehicle in Workshop
W hen working on a vehicl e in the workshop al ways make sure t hat :
W here practi cable, t he parking brake is appli ed and t he wheel s are securely chocked to prevent t he vehi cl e movingforwards or backwards .W henever pos si ble, t he ignit ion key i s removed before any work is carried out on t he vehi cle.If the engine i s t o be run, t here i s adequat e vent il ati on, or an extract ion hos e i s us ed to remove exhaus t fumes.There i s adequat e room to rais e the vehicle and remove t he wheel s , if neces s ary.Fender covers are al ways ins tal led i f any work i s to be carri ed out in t he engine compart ment.W here practi cable, t he batt ery i s dis connected if worki ng on the engi ne, underneath t he vehicle, or if t he vehi cl e i srai sed.
• CAUTIO NS:
Prior to dis connect ing the bat tery, refer to the El ect ri cal Secti on of this manual - Bat tery dis connect ion/connect ion.For addit ional informat ion, refer t o: Specificati ons (414-01 Bat t ery, Mount ing and Cables , Speci ficat ions).
W hen el ect ri c arc wel ding on a vehi cl e, al ways dis connect t he generator wi ri ng to prevent t he pos si bili ty of a s urgeof current caus i ng damage to the i nternal component s of the generat or.
If us i ng welding equipment on t he vehicle, a s uit abl e fire exti nguis her is readily avail able.
Battery - General
• CAUTIO NS:
Prior to carrying out any procedures which i nvol ve dis connect ing/ or connecti ng the bat tery, refer t o t he ElectricalSect ion of t his manual - Batt ery di sconnect ion/connect ion.For addit ional informat ion, refer t o: Specificati ons (414-01 Bat t ery, Mount ing and Cables , Speci ficat ions).
A di s charged bat tery condit ion may have been caus ed by an electrical short ci rcuit . If t his condit ion exis t s there wil lbe an apparentl y li ve circuit on the vehicle even when al l normal circuit s are s wit ched off. This can cause arcing when t hejumper cables are connect ed.
W hi le it i s not recommended that the vehicl e is jump s t art ed, i t is recognized t hat thi s may occas ionall y be t he onl ypracti cal way t o mobi lize a vehi cl e. Prior t o at tempt ing a jump s t art , reference must be made to the El ect ri cal Secti on oft hi s manual - Jump St art ing.
Followi ng jump s tart ing of a dis abl ed vehi cle, the di s charged bat tery mus t be checked for s erviceabili ty and recharged offt he vehi cl e as s oon as poss ibl e t o avoi d permanent damage.
Do not rel y on t he generator t o res t ore a di s charged bat tery. For a generat or t o recharge a batt ery, it woul d take i n exces sof eight hours cont inuous dri vi ng wi th no addi ti onal loads placed on t he batt ery.
Always make s ure that t he jumper cabl es are adequate for the tas k.Always make s ure that t he s lave batt ery i s of the same vol tage as t he vehicle bat tery. The bat teries mus t beconnected i n paral lel.Always make s ure that s wit chabl e electric circui ts are s wi tched off before connecti ng jumper cabl es. This reducest he ri sk of arci ng occurring when the final connecti on is made.
Towing the Vehicle
W ARNING: W hen t owing i s neces sary, reference mus t be made to the Jacki ng, Lift ing and Towing Secti on of thi sManual .
W hen t he vehicle i s being t owed dock the remote cont rol and s wit ch on the ignit ion. (s t eering l ock releas ed and warni ngli ght s i ll uminated). Onl y t hen wil l the s t eering, turn s ignal lamps , horn and s t op lamps be operat ional. Fail ure t o followt hes e i nst ructi ons may res ult in pers onal injury. It mus t be noted that wit h t he engine not running, t he power s t eering andbrake boost er wil l be inoperat ive t herefore, great er effort wil l be needed t o s t eer t he vehicle and apply the brakes .
General Installation Instructions
Component removal
W henever pos si ble, clean component s and the surroundi ng area before removal .
Blank off openings expos ed by component removal .Followi ng dis connecti on, s eal fuel, oil or hydrauli c li nes i mmediat ely us ing sui table bl anki ng plugs or caps .Seal open ends of expos ed oil ways us i ng sui table tapered hardwood pl ugs or cons pi cuous pl as t ic pl ugs .Immediat el y a component i s removed, place it i n a sui table contai ner; us e a s eparate cont ai ner for each componentand it s as s ociat ed part s .

Marki ngs are us ual ly provi ded on t he hos e t o i ndi cat e t he correct cli p posi ti on. If no markings are provi ded, pos it ion t heclip direct ly behind t he ret aini ng li p at the end of t he s tub pi pe. W orm dri ve clips s hould be orient at ed wi th the crimpeds ide of t he dri ve hous ing facing t owards t he end of the hos e or t he hos e may become pi nched bet ween the cli p and t hes tub pi pe ret aining l ip. Unles s ot herwis e s t ated, worm dri ve cl ips s hould be ti ght ened to 3 Nm (2 lb-ft). Make s ure t hathose cl ips do not foul adjacent components .
Oeti ker cl ips may be removed by bendi ng the tag (arrowed) and releas ing t he free end of t he cl ip. Cli ps mus t not bereus ed. W hen ins t al li ng new cli ps , make s ure cl ip is pos it ioned on hose before ti ghtening and make s ure that when cli p ist ightened, the t ag is locat ed i n t he longit udi nal s lot i n t he free end of the cl ip (arrowed in il lus trat ion).
Heat protect ion
Always make s ure that heats hields and protecti ve s heat hing are in good condit ion; replace i f damage i s evident. Part icularcare mus t be t aken when rout ing hos es cl ose to hot engine component s s uch as the exhaust mani fol ds and exhaust gasrecircul ati on (EGR) pipes . Hoses will relax and defl ect s l ightl y when hot, make s ure thi s movement is t aken into accountwhen rout ing and s ecuring hos es .
Electrical Precautions
General
The fol lowing gui del ines are int ended t o make s ure the safet y of t he operator whil s t prevent ing damage t o t he electricaland electroni c component s of this vehi cl e.

Environmental Precautions
This s ecti on provides general informati on which can help t o reduce t he environment al i mpact s from the act ivit ies carriedout in workshops .
Emis s ions t o air
Many of the act ivit ies t hat are carried out i n works hops emit gas es and fumes whi ch can contribut e to global warmi ng,depl eti on of the ozone layer and/or the format ion of phot ochemical s mog at ground level.

Exhaus t fumes
Runni ng car engines i s an es sent ial part of works hop act ivi ti es and exhaust fumes need t o be venti lated to at mos phere.However, the amount of t ime engi nes are runni ng and the pos it ion of t he vehi cle s hould be carefully cons idered at al lt imes , to reduce the releas e of poi s onous gas es and mini mis e t he i nconveni ence t o peopl e l iving nearby.
Solvent s
Some of t he cl eani ng agent s us ed are sol vent based and wil l evaporate rapidl y to atmos phere i f used carel ess l y, or i fcont ainers are l eft unseal ed. Al l contai ners mus t be firmly cl os ed when not requi red and s olvent should be used sparingly.W herever poss i bl e, sol vent s havi ng a l ow t oxi ci ty and flammabi li ty should be sel ect ed.
